  • 1/4 in hose barb fits standard inner-diameter hose for quick installation
  • Nitrile seal material maintains reliable sealing across rated temperature and pressure ranges

SPEEDAIRE 30E629 Quick Connect Socket

The SPEEDAIRE 30E629 is a push-to-connect socket designed for 1/4 inch hose barbs. Its aluminum body with an anodized finish provides durability for pneumatic and fluid transfer applications. The integrated poppet valve automatically controls flow when connecting or disconnecting lines. It suits technicians needing rapid, tool-free coupling changes on compressed air or fluid systems.

Integrated Poppet Valve and Nitrile Seal

The built-in poppet valve seals the connection instantly upon engagement, preventing unwanted air or fluid loss during hose swaps. A nitrile seal ensures compatibility with common pneumatic oils and compressed air within rated specifications. The push-to-connect locking mechanism allows single-handed operation without separate tools or clamps. This combination reduces downtime when reconfiguring workshop air lines or mobile equipment.

1/4 Inch Barb Capacity and Flow Rating

The socket accepts 1/4 inch inner diameter hose, delivering a maximum flow rate of 1,41 within its rated pressure and temperature range. It handles standard shop air compressor outputs and common fluid transfer duties without restriction. The aluminum construction resists corrosion but is not rated for extreme chemical exposure or high-vibration environments without additional support. Systems requiring larger bore connections or higher flow volumes will need a different coupling size.

Questions about this item

When should the nitrile seal be replaced on the 30E629 socket?

Inspect the nitrile seal whenever you disconnect the 1/4 inch barb; replace it if the seal shows cracking, flattening or permanent deformation to maintain the poppet valve's shut-off performance.

What pressure or flow limit appears first during continuous pneumatic use?

The integrated poppet valve and 141 maximum flow rating set the practical ceiling; sustained demand above that rate will cause pressure drop across the coupling before any other component reaches its limit.

How much heat does the aluminum body generate when the coupling runs all day?

The anodized aluminum body does not generate heat itself; it simply conducts the temperature of the compressed air or fluid passing through the 1/4 inch barb, so downstream air prep determines the surface temperature.
