SPEEDAIRE 30E655 Coupler Body
The SPEEDAIRE 30E655 is a hose coupling body designed for pneumatic systems requiring 1/4 inch NPT male threaded connections. It suits technicians and operators who need reliable quick-connect fittings for compressed air or nitrogen lines.
Zinc Plated Steel Construction
The coupling body is made from zinc plated steel for corrosion resistance in shop environments. A sleeve locking mechanism allows connection and disconnection without hand tools. An internal poppet valve controls air flow automatically during coupling and uncoupling. The 1/4 inch -18 NPT male thread fits standard port sizes.
ARO Standard Interchange
This coupler follows the ARO standard interchange type for compatibility with matching nipples. Nitrile seals perform across a rated temperature range of -40°F to 150°F. Maximum working pressure is rated at 300 psi at 70°F. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item
What does the 1/4"-18 NPT thread limit in practice?
It mates with 1/4" NPT female ports and caps the connection at the 300 psi rating at 70°F.
What clearance does the 1/4" body and male fitting need to mount?
The anodized aluminum body with silver finish requires a 1/4" NPT female thread and enough wrench flats for the male fitting.
How is the sleeve locking mechanism installed, and what step is often missed?
Thread the male NPT end into the port with sealant, then verify the poppet valve seats and the sleeve locks without hand tools.
