The Miller Edge RAH-500 is a 1/2 in. inside-diameter pure gum rubber air hose used in non-monitored air-activated sensing edge systems. It is the hose size used in several PS20K500 pneumatic kit listings and is also common in Air-Wave style field repairs.
This pure gum rubber air hose is used as part of an air-pressure sensing system, not as an electrical contact edge by itself. Correct fitment depends on the hose inside diameter, wall thickness, switch style, plugs, and whether the system is Air-Wave or pneumatic.
RAH-500 is often selected because it is used in PS20K500 pneumatic kits, but the hose alone does not determine compatibility. The switch, plug, tubing route, and operator safety input all need to agree with the original installation.
For current operators that require monitored entrapment protection, do not install a non-monitored air hose system as the primary required safety device. Consult a qualified technician when updating an older door or gate operator.
A: RAH-500 is 1/2 in. inside-diameter gum rubber air hose used in Miller Edge Air-Wave and pneumatic sensing edge systems.
A: Yes. PS20K500 kits are associated with 1/2 in. RAH-500 gum rubber hose in 12 ft. and 18 ft. versions.
A: P-50 and P-50H are the related Miller Edge plug styles for RAH-500 and RAH-375 hose.
A: Only if the system fittings and edge design are intended for 1/2 in. hose. The inside diameter must match the original build.
A: No. RAH-500 is hose used in a non-monitored air-activated sensing edge system.
