Upgrade & Restore Your Tire Changer's Pneumatic Air Flow

The 1"/4" NPT X 3"/8" Tube Straight Fitting is a premium pneumatic connector designed to direct compressed air flow reliably to foot pedal control valves, air manifolds, and cylinder assemblies inside professional tire changers.

Corrosion from moisture in shop air lines can cause brass fittings to crack or leak. This direct-replacement fitting ensures a perfect, leak-proof pneumatic seal to maintain constant system pressure (up to 175 PSI).

Machine Location:

This fitting threads directly into the pneumatic foot pedal control valves, main air regulator, or helper arm valves.

Key Features & Specifications

• Machined Solid Brass: Forged and machined from corrosion-resistant solid brass to tolerate continuous moisture.
• Precision Tapered Threads: Tapered NPT or fine threads ensure tight metal-to-metal sealing under pressure.
