Question by: Darryl H on Apr 26, 2025, 3:33 PM

these couplings safe to run on a water line too, or just air?

Answer by: Customer Support on Apr 27, 2025, 5:03 PM

Air and water service are both fine for this coupling. Just keep in mind it's not rated for steam, so don't put it anywhere near a steam line. Pressure ceiling is 150 PSI at 70 degrees F, and the temperature range with the standard rubber washer runs from -20 up to 160 degrees F.

Hey, will this here fitting work okay for hooking up my air compressor to my hose? Just wanna make sure it's the right size before I order.

This universal air hose coupling with a 3/4 inch ID hose barb should fit just right for connecting your air compressor to your hose, as long as your hose also has a 3/4 inch inner diameter.

got a 3/4 inch air hose here, will that barb on the HE-75 actually match up right?

Answer by: Customer Support on Aug 31, 2025, 7:51 PM

The HE-75 is the 3/4 inch ID hose barb size, so it’s intended to go into a 3/4 inch inside diameter hose.
