Gas Chimney Vent Pipe and Fittings

For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.

To join pipes and connectors, insert a male end into a female end and secure with the included locking band.

Adjustable Inline Pressure-Relief Valves for Chemicals

With a three-port design, these valves allow inline flow from the inlet to the outlet during normal conditions and divert flow through the relief port in overpressure conditions. Often used with feed pumps for fertilizers and bleach, they have a PVC body and a PTFE seal for excellent chemical resistance. The relief port begins opening at the set pressure and fully opens at about 10% over the set pressure. It begins closing as pressure drops and fully closes when the system pressure is restored below the set pressure, resuming inline flow from the inlet to the outlet. Adjust the set pressure within the range.

Pressure-Relief Valves with Push-to-Connect Fittings for Air

For a low-pressure seal around plastic and soft metal tubing, these valves have push-to-connect fittings. They allow inline flow from the inlet to the outlet during normal conditions and divert flow to the relief port in overpressure conditions. The relief port begins opening at the set pressure and fully opens at about 10% over the set pressure. It begins closing as pressure drops and fully closes when the system pressure is restored below the set pressure. The vented relief port exhausts discharge directly. Set pressure is not adjustable. Valves are color coded based on the set pressure for easy identification.
