37° Flared JIC Fittings — 316 Stainless Steel

About JIC Nuts, Tube Caps and Plugs

Not every JIC part joins two lines. This group covers the components used to terminate, blank off or complete a 37° flare joint. A tube cap fits over the 37° nose of a male JIC fitting to seal an unused port. A tube plug works the other way round, sealing into a JIC nut or female flare to close the end of a tube line. The tube cap assembly combines the cap and nut as one item, and the loose nut is offered separately for building or repairing flared tube assemblies.

These parts come into play during commissioning, pressure testing and maintenance. Capping an open fitting keeps dirt out of a hydraulic system while a component is removed, and plugging a branch lets one section of a circuit be tested or isolated without stripping it back. Because they use the same 37° metal-to-metal seat as the rest of the JIC range, a correctly sized cap or plug seals in the same way as a working connection.

All items are SS316 and the group covers sizes from 1/8" to 2", so blanking parts can match the material of the surrounding stainless pipework instead of introducing a dissimilar metal.

• Cap a male 37° nose; plug a female flare or nut.
• Match the dash size exactly so the cone seats correctly.
