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

Product Description

The COILHOSE PNEUMATICS 8803K is a tamper-proof, heavy-duty T-handle compressed air regulator built for demanding industrial and shop air applications. It features a 3/8 inch NPT port and handles a maximum supply pressure of 250 psi, with an output pressure range of 0 to 125 psi. The cast aluminum body provides durability under continuous use. A built-in relief function allows pressure to bleed off when the set point is reduced, making it suitable for regulated air systems that require precise, stable downstream pressure. At 40 CFM maximum airflow, this regulator supports high-demand pneumatic tools and equipment. A 1/4 inch gauge port is included for optional pressure gauge installation.

The 8803K suits fixed-point installations in industrial facilities, manufacturing lines, maintenance shops, and commercial service environments. It is well suited for compressed air distribution systems where downstream pressure must be set and locked to prevent unauthorized adjustment. The tamper-proof T-handle design makes it appropriate for shared tool stations, compressor drops, and pneumatic control circuits where consistent regulated pressure is critical to tool performance and operator safety. Licensed industrial mechanics and pneumatic system technicians are the typical installers for this type of regulator.

Key Features

• Tamper-proof T-handle design prevents unauthorized pressure adjustment at shared air stations
• 3/8 inch NPT end connections for direct inline installation on standard compressed air drops
• 250 psi maximum supply pressure with 0 to 125 psi adjustable output range
• 40 CFM maximum airflow supports high-volume pneumatic tools and equipment
• Built-in relief function bleeds downstream pressure when set point is lowered
• 1/4 inch gauge port accepts an optional pressure gauge for downstream monitoring
• Cast aluminum body for lightweight durability in fixed installation environments

Compatibility

Designed as an inline compressed air pressure regulator for standard 3/8 inch NPT compressed air distribution systems with supply pressures up to 250 psi. Part of the Coilhose Pneumatics Series 88 regulator line.

Installation Notes

Install by a qualified pneumatic systems technician or industrial mechanic. Depressurize and lock out the compressed air supply before installation or removal. Apply thread sealant appropriate for compressed air service to all NPT connections and tighten to fitting standards without overtightening cast fittings. Verify downstream pressure with a calibrated gauge before returning the system to service.
