Coilhose Pneumatics 8803KH Air Regulator 3/8 Npt 250 Psi

Product Description

The COILHOSE PNEUMATICS 8803KH is a heavy-duty tamper-proof compressed air regulator built for demanding industrial and shop applications. Featuring a 3/8 inch NPT port and a maximum supply pressure rating of 250 psi, it delivers a regulated output range of 0 to 200 psi. The T-handle design resists unauthorized adjustment, making it well suited for shared tools, production lines, and service bays where consistent downstream pressure is critical. Cast aluminum construction keeps weight low while standing up to the mechanical demands of continuous pneumatic service. Maximum airflow capacity is 40 CFM. A 1/4 inch gauge port thread is included for optional pressure gauge installation.

The 8803KH is designed for compressed air systems requiring reliable pressure regulation in light industrial, manufacturing, and maintenance environments. It fits inline with standard NPT pneumatic plumbing and is appropriate for use upstream of air tools, spray equipment, and automated pneumatic circuits. The tamper-proof T-handle makes it a practical choice wherever a set pressure must be maintained without risk of casual readjustment. Licensed pneumatic system installers, industrial maintenance technicians, and experienced shop mechanics are the typical end users.

Compatibility

Designed as an OEM-style inline regulator for compressed air systems using 3/8 inch NPT plumbing. Part of the COILHOSE PNEUMATICS Series 88 regulator line.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems professional. Depressurize and lock out the air supply before making any connections. Apply appropriate thread sealant to NPT fittings and verify all connections are leak-free before restoring supply pressure. Position the regulator with the airflow direction matching the arrow or inlet marking on the body.
