The SS304 Stainless Steel Pneumatic Adaptor Fittings are high-performance push-to-connect

fittings engineered for tube-to-thread connections in harsh industrial environments.

Constructed from corrosion-resistant 304 stainless steel (AISI 304), these fittings are ideal for

applications requiring superior durability vs. brass alternatives, and support both BSPT (tapered)

and BSPP (parallel) thread standards in male/female configurations. Available in three core

models (PC male straight, PCF female straight, PC G male with O-ring seal), they are optimized

for 4-12mm metric pneumatic tubes and suitable for food processing, chemical, marine, and

high-humidity pneumatic systems.
