Miller Edge RAH-375 Pure Gum Rubber Air Hose - 100 ft. - 3/8" ID, 1/8" Wall
The Miller Edge RAH-375 is a pure gum rubber air hose used to build or repair air-activated sensing edge assemblies. It has a 3/8 in. inside diameter and a 1/8 in. wall and is supplied here as a 100 ft. roll.
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.
Compatible With
- Miller Edge Air-Wave and pneumatic switches when the hose diameter and fittings match
- Miller Edge Air-Wave configured sensing edges and treadles using compatible air hose
- Miller Edge pneumatic configured sensing edges and treadles using compatible air hose
- Bulb seal and loop seal applications that require this hose diameter and material
- Older commercial door and gate applications originally designed around non-monitored air-activated sensing edges
- AW10, AW12A, and AW14 Air-Wave switch applications when the edge is built for 3/8 in. hose
- PS20A pneumatic switch applications when 3/8 in. gum rubber hose and the correct fittings are used
- P-50 and P-50H hard rubber plugs for RAH-375 and RAH-500 hose
- 218-27-18 barbed elbow connector when used with the correct holed plug and tubing layout
- Not compatible with P-75 or P-75H plugs, which are for RAH-750 3/4 in. hose

Technician Note
RAH hose size matters. A 3/8 in. hose, 1/2 in. hose, and 3/4 in. hose may look similar in photos, but the plugs and fittings are not interchangeable across every size.
Before Ordering Checklist
- Measure the old hose inside diameter before ordering.
- Confirm whether the system uses Air-Wave or pneumatic switching.
- Check the plug style at the end of the hose.
- Inspect for cracks, dry rot, blocked hose, or leaking end plugs.
- Confirm the operator can use the existing non-monitored air-activated edge system.
Professional Advisory
Do not operate a powered door or gate with a damaged or disconnected safety edge. If a replacement hose does not restore proper reversing action, have the switch adjustment, wiring, and operator input inspected by a qualified technician.
