Product identity
The Westward 400007 is a 3/8 NPT bushing supplied under the Speedaire brand. It serves technicians and maintenance teams who need a reliable threaded fitting for compressed-air or vacuum lines.
Thermals noise and power
As a passive metal fitting the bushing generates no heat, produces no audible noise and draws no electrical power. Its operation is limited to the pressure and temperature ratings of the piping system it joins.
Build integration
The 3/8 NPT threads connect directly to matching pipe or hose ends without extra adapters. No power supply, controller or software is required, freeasing bench space and wiring complexity for other equipment.

Questions about this item
How do I install the 3/8 NPT bushing without cross-threading?
Clean both threads, apply PTFE tape clockwise on the male end, hand-tighten the bushing, then finish with a wrench turn of one to two flats — over-tightening is the common mistake.
When will the 3/8 NPT bushing need replacement?
Inspect annually; replace if threads show galling, the seating face is scored, or air leaks appear at the joint — brass-on-steel connections typically last years under normal shop pressure.
What pressure limit appears first during continuous compressor cycling?
The 3/8 NPT thread rating governs; sustained operation near the fitting's maximum working pressure will show leakage at the joint before the brass body yields.
