Water-Tite Multi-Cap Type B Vent Cap
The Water-Tite 81695 vent cap focuses on keeping the vent clear and protected. Best for homeowners needing a reliable cap with a non-clogging draft design. The clamp fittings are adjustable to fit standard sizes, and the heavy-duty aluminum construction helps resist rust and corrosion over time. This option is well-suited for vent terminations exposed to the elements or where venting efficiency matters most. A potential limitation is that it is a cap component rather than a full elbow or pipe assembly, so pairing with compatible pieces is necessary.
105036 Gas Chimney Pipe, 5″ x 3′
This 5″ x 3′ gas chimney pipe from Selkirk Sport Store is designed for straightforward assembly and expandable height by combining sections. It suits installations where space constraints require adjustable length and easy on-site modification. The couplers overlap by 1-1/2″ when joined, providing a secure seal. Best for projects needing a modular approach to reach the desired vent height; consider the overall run length to avoid excessive joint counts.
DuraVent 5BVL90 5 in. Elbow
The DuraVent 5BVL90 elbow offers a tight-turn, 90-degree option for navigating around obstructions. It features double-wall construction for added durability and better insulating properties. It is best for installations where offsets are needed to clear framing or other obstacles. A potential limitation is that specific dimensions and compatibility with certain vent systems should be confirmed to ensure a proper fit in existing runs.
90° Universal Vent Cap (PVC Termination)
The PVC termination option provides a sturdy vent end with a stainless-steel screen for debris defense. Best for installations using 2″ to 5″ PVC pipes where a straightforward, low-profile cap is desired. It is a good fit for simple vent terminations; however, installation suitability depends on your system’s material compatibility and local codes. Choose this when you need a basic, corrosion-resistant cap without complex hardware.
Selkirk PP VNT Gas 5IN 5FT Direct Vent Pipe
The Selkirk 5IN direct vent pipe is designed for direct vent gas systems and combines ease of use with high durability. Best for projects requiring a sturdy, United States-made vent component with straightforward assembly. It is suitable for longer vent runs when combined with compatible connectors. A consideration is ensuring the pipe length aligns with code requirements and the rest of the vent system.
Buying Guide: Key Considerations For 5 Inch B Vent Components
