The best 3/16-inch pilot tubing depends on the appliance, required length, fittings, and whether you need a tube alone or a valve-and-tube assembly. The Robertshaw 5-foot line is best for buyers seeking tubing with fittings; the Vulcan-Hart tube is a shorter option with a pilot head; and the DRELD and SURIEEN assemblies offer 20-inch tubing with additional parts. The GSW option is 27 inches long and bendable. Confirm the existing part’s measurements and appliance model before choosing a replacement.

Robertshaw 3/16-Inch x 5-Foot Tubing
This Robertshaw Store product is listed as 3/16-inch pilot burner tubing measuring 5 feet long, supplied with fittings. Its length distinguishes it from the shorter, fixed-length replacement assemblies in this selection.
Best for: Buyers whose repair requires a longer piece of tubing and who want fittings included. The 5-foot length may suit a job where a short preassembled tube would not provide the needed reach, subject to the appliance’s required routing and connection details.
Why it was selected: It directly matches the 3/16-inch pilot tubing search and provides a clear length and included-fittings description. It may be a simpler choice than a valve kit when the existing valve is not being replaced.
Limitation: The supplied product information does not specify the fitting types or appliance compatibility. Check those details against the original part before ordering; do not assume the fittings match a particular appliance.
Vulcan-Hart 18-Inch Pilot Tube
The listed Vulcan-Hart 421573G4 is a 3/16-inch pilot tube with a head, measuring 18 inches long. The supplied product details identify it as a Vulcan-Hart pilot burner component.
Best for: Buyers who need an 18-inch tube with a head and can verify that the part matches their appliance. Its defined length and included head make it more specific than generic tubing sold by length.
Why it was selected: It is a direct fit by the search’s 3/16-inch tubing dimension and is identified as a pilot tube with head. Choose it when those features align with the original part rather than selecting by tubing diameter alone.
Limitation: The provided listing information does not include a detailed compatibility list or describe other included fittings. Confirm the model number and connection arrangement before purchase.
DRELD 20-Inch Tube with Pilot Valve
DRELD lists this product as a 3/16-inch outside-diameter, 20-inch copper pilot tube. The described assembly includes a pilot tip, nut, sleeve, and 2065641 pilot valve. The listing says the tube can be bent and that excess length can be cut off.
Best for: Buyers replacing a 20-inch tube who also need the listed valve and connection hardware. The listing names several appliance and component references, including 2065641 and 521061, and identifies a range of commercial equipment models.
Why it was selected: It combines a defined tube size with several named parts and a compatibility list, which helps buyers compare the assembly with an existing component. Check every model and part reference against the appliance documentation.
Limitation: A long compatibility list does not establish a match for every appliance in a brand’s range. The listing also describes cutting the tube, so buyers should verify the required length and connection setup before modifying it.
GSW 27-Inch Bendable Pilot Tubing
GSW lists this tubing as 3/16-inch outside diameter and 27 inches long, with a pilot tip, nut, and sleeve. The product description calls the tubing copper-clad aluminum and says it can be bent and cut to suit an installation.
Best for: Buyers who need more length than a 20-inch tube provides and want a bendable assembly with the tip and listed hardware. The listing also describes it as a Chinese wok range accessory for commercial restaurant kitchen gas equipment.
Why it was selected: Its 27-inch length makes it a distinct option among the products here, while the stated contents give buyers a useful checklist for comparison with the original part.
Limitation: The supplied details do not identify specific appliance models or provide a full connection specification. Confirm the tubing material, connections, and equipment match before choosing it.
SURIEEN Two-Tube Pilot Assembly
SURIEEN describes this product as a set of two 3/16-inch outside-diameter, 20-inch copper pilot tubes with tip assemblies and a double pilot valve. The listed valve has a 1/8-inch NPT inlet and 3/16-inch tubing outlet. The listing says the tubes can be bent and excess length can be cut.
Best for: Buyers who need two tubes and a double pilot valve as part of one replacement set. Its listed dimensions and valve connections offer specific details to compare with the removed assembly.
Why it was selected: It is the only option here explicitly described as including two tubes and a double valve. Its compatibility information names several commercial appliance series and related pilot components.
Limitation: This is a broader assembly than a tubing-only replacement. If the existing valve does not need replacement, compare the parts required before buying the set. Verify the appliance model and connection dimensions rather than relying only on a brand name.
Buying Guide: How to Choose 3/16-Inch Pilot Tubing
What does 3/16 inch refer to?
For several products in this selection, 3/16 inch is explicitly identified as the tube’s outside diameter, or O.D. Do not assume every listing uses the measurement in the same way unless its description says so. Compare the replacement’s stated dimension with the original tube and appliance documentation. A matching diameter alone does not confirm that the length, end fittings, tip, or valve connections are correct.
How long should the pilot tube be?
Start with the length of the original assembly and the route it takes through the appliance. The products here range from 18 inches to 27 inches, while the Robertshaw tubing is 5 feet long. A longer tube may provide extra material, but it is not automatically a suitable replacement. Confirm the needed route and connection positions before selecting a fixed-length assembly or tubing that may be cut.
Do you need tubing only or a complete assembly?
Choose according to which parts actually need replacement. The Robertshaw product is described as tubing with fittings. The Vulcan-Hart product is a tube with a head. DRELD lists a tube, pilot tip, nut, sleeve, and valve; GSW lists a tip, nut, and sleeve; SURIEEN lists two tubes, tip assemblies, and a double pilot valve. Compare each package with the parts being removed to avoid selecting an incomplete or unnecessarily broad set.
Why check the connections and valve?
Pilot tube assemblies connect components in a gas appliance, so the connection type is a key selection detail. SURIEEN gives specific valve inlet and outlet dimensions, and DRELD identifies a pilot valve and related component references. The other product information is less detailed about connections. Match the connection type and part number to the original component or the manufacturer’s appliance information; do not infer a match from tubing diameter alone.
Does bendable or cuttable tubing make installation simpler?
DRELD, GSW, and SURIEEN describe their tubes as bendable, and their listings mention cutting excess length. Those features can offer flexibility when the required route differs from a straight line, but the listing language does not establish that a product fits every appliance. Follow the appliance manufacturer’s instructions and use an appropriately qualified technician for gas-appliance work. Do not alter a tube unless the product and appliance instructions allow it.
How should you verify compatibility?
Use the appliance model and the part number on the existing component as the main references. Compare tube diameter, length, tip or head style, fittings, and valve connections. DRELD and SURIEEN supply model or component lists, but those lists should be checked against the exact appliance. For Robertshaw and Vulcan-Hart, the provided product details do not give an extensive compatibility list. Ask the manufacturer or a parts supplier when the match remains unclear.
Frequently Asked Questions
Is 3/16-inch pilot tubing the same as a 3/16-inch tube outside diameter?
Not necessarily based on the search phrase alone. Several listings explicitly state 3/16-inch O.D.; verify that the measurement refers to the outside diameter for the product you are considering.
Can pilot tubing be cut to length?
DRELD, GSW, and SURIEEN say their tubing can be cut to remove excess length. Check the product and appliance instructions before cutting, and confirm that the resulting connections remain appropriate.
Which product includes a valve?
DRELD lists a 2065641 pilot valve. SURIEEN lists a double pilot valve with a 1/8-inch NPT inlet and 3/16-inch tubing outlet. Check the required valve part and connection dimensions before choosing either set.
Which option is longest?
The Robertshaw tubing is listed as 5 feet long. Among the fixed-length assemblies, the GSW tube is 27 inches; the DRELD and SURIEEN tubes are 20 inches, and the Vulcan-Hart tube is 18 inches.
Can I choose a replacement based only on tube diameter?
No. Also compare length, fittings, tip or head, valve connections, and appliance model. A matching 3/16-inch measurement by itself does not confirm that a part is compatible.
