1/2 inch Carbon Steel 401G Gas Press Coupling with Stop Press x Press

1/2" Carbon Steel Gas Press Coupling – Apollo PowerPress™ 401G Series

The 1/2" Carbon Steel 401G Gas Press Coupling from Apollo PowerPress™ is engineered for joining ASTM A53, A106, A135, and A795 carbon steel pipe in gas distribution systems using press technology. Manufactured to support the safe transport of natural gas and propane, this coupling features dual press ends and is optimized for use in Schedule 10–40 piping systems.

This fitting incorporates a yellow HNBR sealing element specifically designed for fuel gas applications, providing long-term sealing integrity under elevated pressure and temperature ranges. With a zinc-nickel corrosion-resistant coating and a factory-installed sealing element, it supports faster installations and permanent joints without welding or threading. Apollo's Smart Connect® feature ensures unpressed connections are easily identified during system testing.
