SSP FITTINGS CORP Duolok tube fittings ensure a leak-proof connection in instrumentation and process tubing systems. The advanced double ferrule design allows for compensation across varying tubing materials hardness and tube wall thickness providing robust leak-tight connections across a wide range of applications. Machined from type 316 stainless steel in accordance with ASTM standards these fittings deliver dependable performance.
Precision-engineered for interchangeability with Swagelok fittings Duolok tube fittings offer flexibility and reliability. They are gaugeable ensuring sufficient pull-up during initial installation. Generally they are rated for pressures matching the maximum allowable working pressures of recommended stainless steel tubing although some specially designed fittings may have lower ratings.
Duolok tube fittings operate reliably across a broad range of temperatures but note that elevated temperatures can reduce maximum working pressures. The components are heat code traceable with certified material test reports (CMTRs) available.

It's designed for use with 0.38 inch outside diameter tubing.
Question by: Terry A on Oct 17, 2025, 12:21 PM
got a 3/8 tube standpipe on one side and a 9/16-18 JIC on the other. Is that what this adapter is?
Answer by: Customer Support on Oct 18, 2025, 12:45 PM
For connecting instrumentation or process tubing to JIC flare hardware, this fitting matches a 0.38 inch tube OD standpipe end on one side and a 9/16-18 male JIC 37 degree flare on the other, in a straight configuration.
