Miller Edge RAH-750 Pure Gum Rubber Air Hose - 100 ft. - 3/4" ID, 1/8" Wall
The Miller Edge RAH-750 is the larger 3/4 in. inside-diameter pure gum rubber air hose in the RAH hose family. It is used where a Miller Edge Air-Wave or pneumatic sensing edge system was designed for 3/4 in. air hose.
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 applications when built for 3/4 in. hose
- PS20A pneumatic switch applications only when the correct 3/4 in. fittings and adapters are used
- P-75 and P-75H hard rubber plugs for RAH-750 hose
- Select Air-Wave kits and pneumatic builds using 3/4 in. hose
- Not compatible with P-50 or P-50H plugs, which are for RAH-375 and RAH-500

Technician Note
RAH-750 requires the 3/4 in. plug family. A common field mistake is trying to reuse smaller P-50 style plugs on RAH-750 hose, which can cause poor sealing or an unreliable air signal.
Before Ordering Checklist
- Confirm the existing hose is 3/4 in. inside diameter.
- Use P-75 or P-75H plugs where a Miller Edge plug is required.
- Confirm the switch tubing and adapters match the larger hose size.
- Check the old hose for splits, flattening, dry rot, or loose plugs.
- Confirm the operator and edge system are intended for a non-monitored air edge.
Professional Advisory
Air leaks can stop a pneumatic edge from reversing the door or gate correctly. If the edge fails after replacing hose or plugs, stop using the operator until the air path and safety input are tested.
Product Questions & Answers
Q: What is RAH-750 used for?
A: RAH-750 is 3/4 in. inside-diameter gum rubber air hose for select Miller Edge Air-Wave and pneumatic sensing edge systems.
Q: Which plugs fit RAH-750?
A: RAH-750 uses the P-75 and P-75H plug family, not the P-50 or P-50H plug family.
Q: Can RAH-750 replace RAH-500?
A: No, not unless the edge, fittings, and switch connection are redesigned for 3/4 in. hose. The diameters are different.
Q: Can RAH-750 be used with PS20A?
A: It may be used in PS20A pneumatic applications only when the correct 3/4 in. hose fittings and adapters are part of the system.
Q: Is this a complete sensing edge?
A: No. RAH-750 is hose only and must be used with the correct switch, plugs, and edge assembly.
