The MMTC Pneumatic 3/8" ID Thick Wall Service Station Grade Treadle Signal Hose is a heavy-duty air pathway designed for driveway and service-bay signaling systems. Laid across a traffic lane and connected to a bell pump, air switch, or diaphragm-operated signal, it generates a pressure pulse when a vehicle rolls over the hose, activating an alert for attendants in fueling areas, repair shops, warehouses, car washes, and drive‑thru lanes. Its thick-wall, service-station construction is built to withstand repeated vehicle passes and abrasion in demanding commercial environments.
Optimized for 3/8" inside-diameter pneumatic circuits, this replacement hose integrates with MMTC treadle and driveway signal components and many legacy driveway bell systems that accept 3/8" ID tubing. It’s an ideal replacement or upgrade for pneumatic driveway alarms in residential or commercial applications. Installation is straightforward: cut to the needed length, push onto compatible barbed fittings, secure if required, and route away from sharp edges or pinch points; no electricity or programming is involved. Use only for low-pressure signaling; do not use for fluids or as a compressed air supply. Inspect periodically for wear and leaks to maintain reliable actuation.
