JIC 37° Flare & Uno (O Ring Boss) Threads
- JIC is JOINT INDUSTRIES COUNCIL – SAE J514, ISO 8434-2
- UN is UNIFIED NATIONAL – SAE J1926, ISO 11926-2
- JIC & UNO (O Ring Boss) thread forms are the same (ASME B1.1). Method of sealing differs.
JSEAL™ is a RYCO proprietary connection that is fully interchangeable and backwards compatible with standard JIC connections.
With a repositioned strike zone away from the male tip, JSEAL™ design drives unrivalled performance, eliminating sweating, cracking, and stretching, while simplifying installation.
The design of JSEAL™ features a convex female seat that is engineered to be used with any JIC Male connection.
JIC male has 37° flare which seals against 37° seat in female.
JIC male can also seal against 37° flared tubing with JIC nut and sleeve.
JIC male can also be used with RYCO S134 J-Lok Female Nut and Flareless Olive on Imperial OD tubing.
UNO (O Ring Boss) seals with O Ring compressed between hex boss of UN male and 12°/15° tapered bore of UN (O Ring Boss) female port.
For elbows and tees, Backup Washer and Lock Nut allow orientation of fitting to required direction.
