RJT Union Hose Tail — Double-Swaged, 304 Stainless Steel
An RJT union hose tail combining a pre-welded RJT liner end with a double-swaged (twin-bead) straight hose shank in 304 stainless steel. It connects flexible process hose directly to an RJT male threaded union port using a standard RJT union nut and O-ring seal. Available in 2 inch (50.8 mm) and 3 inch (76.2 mm) nominal sizes with a 120 mm overall length.

Product overview
Pre-Welded RJT Liner & Double-Swaged Hose Shank
This one-piece hose adapter integrates a stepped RJT union liner face on the coupling end and a cylindrical hose tail machined with two raised circumferential retention beads (double-swaged profile) on the hose end. The pre-welded liner eliminates field welding between a separate RJT liner and hose tail.
Mating RJT Union Components & Hose Retention
On the union side, the stepped liner shoulder seats against an RJT O-ring seal inside a mating RJT male part and is drawn tight by a hexagonal RJT union nut (supplied separately). On the hose side, match the 50.8 mm (2") or 76.2 mm (3") shank outside diameter to the flexible hose bore and secure the hose over the twin retention beads with appropriate band clamps or crimp ferrules.
Listed Sizes, Envelope Length & Wall Thickness Selection Note
The specification schedule covers two 304 stainless steel configurations: 2" (50.8 mm shank OD A, 120 mm length B, SKU SDSHWL50#) and 3" (76.2 mm shank OD A, 120 mm length B, SKU SDSHWL75#). Because the product text notes 1.6 mm wall thickness while the table column lists 1.5, confirm critical bore or wall tolerance before ordering if exact inside diameter is required.
Installation Preparation & Routine Inspection
Before clamping the hose, deburr and clean the shank exterior and verify that the RJT liner seating face is free of nicks. Support heavy transfer hoses near the union joint to reduce cantilevered bending loads on the RJT nut and O-ring seal during operation and CIP washdowns.
