Question by: Tammy J on Nov 25, 2025, 12:57 PM
i got 1/4 inch tubing, is this sleeve the right size for it?
Answer by: Customer Support on Nov 26, 2025, 6:14 PM
It matches a 0.25 inch tube outside diameter, so it is sized for 1/4 inch OD tubing.
Question by: Cindy K on May 30, 2025, 1:38 PM

Answer by: Customer Support on Jun 1, 2025, 9:53 AM

got a quarter inch steel tube and need the little sleeve for a JIC 37 flare, is this the right piece?
Answer by: Customer Support on Aug 27, 2025, 3:49 PM
For a 0.25 inch OD tube using a JIC 37 degree flare setup, this part is the sleeve that goes with that style of tube fitting. It’s the Danfoss/Eaton 900605 series steel sleeve, sold under Eaton Aeroquip.
Question by: Joyce C on Mar 7, 2026, 7:51 PM
what exactly is this sleeve used for in a JIC fitting setup? trying to figure out if it's the piece i'm missing before i order
Answer by: Customer Support on Mar 9, 2026, 6:05 AM
In a JIC 37-degree flare assembly, the sleeve slides over the tubing and works alongside the nut to hold the connection together at the flare seat. It's the component that grips the tube and keeps everything lined up when the fitting is tightened down. For 1/4-inch OD tube, this is the right size sleeve to pair with your JIC nut and fitting body.
