SPEEDAIRE 30E680 Quick Connect Hose Coupling 1/4 in Body 3/8 in Hose

SKU CH-PEE5-GESD5

Quick-connect steel coupling with 1/4 in body and 3/8 in hose barb, rated to 300 psi and 991.09 litres per minute

  • Push-to-connect design enables tool-free hose changes
  • Industrial Interchange standard ensures broad plug compatibility
  • 09 L/min maximum flow supports high-demand air tools
  • 300 psi working pressure at 70°F handles tough jobs
  • Steel body with zinc plating resists corrosion in shop environments

Quick Connect Coupling 1/4 in Body

The SPEEDAIRE 30E680 is a push-to-connect hose coupling designed for compressed air lines. It features a 1/4 in body size and a 3/8 in hose barb for direct insertion into matching hose inner diameters. The steel construction with zinc plated finish suits industrial interchange plug compatibility.

Thermals Noise and Power

This mechanical coupling has no electrical power draw and generates no operational noise. It maintains a sealed connection across a rated temperature range of -40°F to 150°F using a nitrile seal. The poppet-type valve controls flow up to a maximum working pressure of 300 psi at 70°F.

Maximum Flow Rate 991.09 L/min

The coupling delivers a maximum flow rate of 991.09 liters per minute, determining the air volume available to downstream tools. Buyers needing higher flow capacity should verify this figure against their compressor output and application demand. The Industrial Interchange standard ensures mating compatibility with corresponding plugs.

Questions about this item

How do I install the 3/8 in hose barb on this SPEEDAIRE coupling, and what step is often missed?

Push the hose fully over the barb until it seats against the coupling body, then secure it with a properly sized hose clamp; the step often missed is tightening that clamp enough to prevent the hose from blowing off at 300 psi.

What maintenance will the nitrile seals and poppet valve need over time?

Inspect the nitrile seals and poppet valve periodically for wear, cracking or contamination; replace the coupling if seals no longer hold pressure or if the valve sticks, especially after exposure to temperatures near the -40°F to 150°F limits.

At what pressure or flow does this 1/4 in body coupling reach its limit during sustained use?

The coupling is rated for a maximum working pressure of 300 psi at 70°F and a maximum flow of 991.09 liters per minute; sustained operation at or above those limits will cause leakage or premature seal failure first.
