DELPHI FITTINGS
Part Number: 319-SS
37° JIC Tube Sleeve (316 Stainless Steel)
Product Overview
The Delphi Fittings Part 319-SS is a 37° JIC Tube Sleeve, a critical component used in conjunction with a 37° JIC Tube Nut (Part #318) to create reliable JIC flare connections with hydraulic tubing. The sleeve is placed on the tube behind the 37° flare before the nut. When the JIC tube nut is tightened onto a male JIC fitting, the sleeve provides crucial backup support to the flared tube, preventing it from collapsing or distorting under compression and ensuring even pressure distribution on the flare. This action helps to create a strong, consistent metal-to-metal seal between the flared tube and the 37° cone of the male JIC fitting. Manufactured from corrosion-resistant 316 stainless steel for demanding environments, the Part 319-SS JIC Tube Sleeve is essential for the integrity of JIC flared tube assemblies in hydraulic systems.

Applications
The Part 319-SS JIC Tube Sleeve is a fundamental component in creating JIC flared tube connections across numerous industries:
- Hydraulic systems in mobile equipment (construction, agriculture, mining).
- Industrial machinery and manufacturing automation.
- High-pressure fluid transfer lines.
- Automotive and transportation systems.
- Any application where rigid hydraulic tubing is connected using JIC 37° flare fittings.
Installation & Usage Guidelines
- Ensure the hydraulic tube is cut squarely and properly deburred.
- Flare the tube end to a precise 37° angle using a quality flaring tool. The flare surface must be smooth and free of cracks or imperfections.
- Slide the JIC Tube Nut (Part #318) onto the tube first, followed by the JIC Tube Sleeve (Part #319-SS). The sleeve should be oriented so its tapered end sits against the back of the flare.
- Align the flared tube end (with nut and sleeve in place) with the male JIC fitting's 37° cone.
- Thread the Tube Nut onto the male JIC fitting by hand until finger tight.
- Use two wrenches: one to hold the male JIC fitting steady and one to tighten the Tube Nut to the recommended torque. The sleeve will ensure the flare is properly supported and compressed against the male cone.
