The Selkirk 108018 is a Type B small diameter double wall round gas vent pipe designed for residential and light commercial gas appliance venting applications. Built under the trusted RV Series lineup from Selkirk by Duravent, this pipe section measures 8 inches in diameter and 18 inches in length. It is constructed from galvanized steel with a wall thickness of 0.012 inches, providing reliable durability in standard venting environments. Type B gas vent pipe is the industry-standard choice for venting natural gas and propane appliances, including furnaces, water heaters, boilers, and unit heaters. The double wall design creates an insulating air space between the inner and outer walls, which helps maintain flue gas temperatures and reduces the risk of condensation inside the vent system. This is a critical feature for efficient draft performance and long-term vent system reliability. The 108018 features Selkirk's LockTab system, a non-positional locking mechanism that allows flexible assembly at any rotational angle. This makes installation faster and easier for HVAC technicians and plumbers working in tight or awkward spaces. Unlike traditional twist-lock systems that require precise alignment, the LockTab design snaps securely without needing to rotate to a specific position. This flexibility reduces installation time on the job site and helps contractors complete work more efficiently. The galvanized steel finish resists corrosion and stands up to the thermal cycling that gas vent systems experience over years of service. HVAC professionals, plumbers, and mechanical contractors rely on the Selkirk RV Series for consistent performance and straightforward compatibility with other RV Series components. This pipe section is ideal for new installations, system extensions, and replacement projects requiring a certified Type B gas vent solution.
The Selkirk 108018 RV Series Type B gas vent pipe delivers reliable double wall venting performance with a flexible LockTab locking system that simplifies installation. It is a durable galvanized steel solution for venting natural gas and propane appliances in residential and light commercial settings.
