The Miller Edge P-75 is a solid hard rubber end plug for 3/4 in. ID RAH-750 gum rubber air hose. In an Air-Wave or pneumatic sensing edge system, the plug helps close the air hose so pressure can travel properly through the hose to the edge switch. This small part matters because the wrong plug size can leak air, weaken edge response, or prevent a pneumatic or Air-Wave safety edge from activating consistently. Use it when the existing assembly uses 3/4 in. ID gum rubber hose and requires the solid end plug style rather than the holed connector style.
Check the hose ID and plug style before replacement. A 3/4 in. hose plug will not seal correctly in smaller RAH-375 or RAH-500 hose, and a solid plug should not be used where the air switch connection requires a holed plug.
Air-Wave and pneumatic sensing edge systems are non-monitored configurations. Do not bypass the safety input or operate a door or gate with a damaged sensing edge. If the operator requires monitored external entrapment protection, have a qualified technician confirm the correct monitored device.
The P-75 is used with 3/4 in. ID gum rubber hose, commonly Miller Edge RAH-750, in Air-Wave or pneumatic sensing edge assemblies.
No. P-75 is the solid end plug. P-75H is the holed version used where a barbed connector or air-line connection is required.
No. RAH-500 is a 1/2 in. ID hose and commonly uses the smaller P-50 or P-50H plug style, not P-75.
This plug is for air hose used in Air-Wave or pneumatic edge systems. It is not a replacement part for electric contact edges.
A loose or wrong-size plug can leak air and reduce the response of an Air-Wave or pneumatic sensing edge.
