Quick-connect coupling for pneumatic lines
The SPEEDAIRE 30E694 is a quick connect hose coupling designed for attachment and detachment of hoses at the end of a hose or air supply line. It uses a push/pull sleeve locking mechanism to secure connections without hand tools. The unit is built for pneumatic and fluid transfer applications and mates with industrial interchange plugs. A barbed hose barb fits 3/8 in hose inner diameter fittings.
Steel body with zinc-plated finish
The coupling body is constructed of steel with a zinc-plated finish for surface protection. A poppet valve works with a nitrile seal to control fluid or air flow when the coupling is engaged. The sleeve mechanism provides connection security during normal operation. No hand tools are required to make or break the joint.
Replaces worn or leaking hose-end fittings
This coupling upgrades from damaged or worn hose-end fittings that leak air or fluid under pressure. The jump is worth it when the existing connection cannot hold a seal or the locking mechanism has failed. It is not for buyers who need a different hose bore size or a non-industrial interchange profile.

Questions about this item
How do I install the 30E694 coupling on a 3/8 in hose and what step is often missed?
Slide the barbed end into the hose inner diameter, then secure it with a hose clamp; the step often missed is tightening the clamp fully so the barbs seal against the nitrile poppet valve.
What maintenance or replacement will the 30E694 coupling need later?
Inspect the nitrile seal and poppet valve for wear or cracking; replace the coupling if the sleeve mechanism no longer locks securely or if air leaks appear at the barb.
What limit appears first on the 30E694 coupling during sustained pneumatic use?
The steel body with zinc plating resists corrosion, but the nitrile seal and poppet valve degrade first under continuous pressure cycles and temperature swings.
