JSEALTM 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, JSEALTM design drives unrivalled performance, eliminating sweating, cracking, and stretching, while simplifying installation.
The design of JSEALTM 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, Back up Washer and Lock Nut allow orientation of fitting to required direction.
