Stainless Steel Duolok Tube Fitting, 0.75 Inch Tube OD Standpipe To 1-1/16-12 Male JIC 37 deg Flare, Straight

Description & Features

The Stainless Steel Duolok Tube Fitting 0.75 inch tube OD standpipe to 1-1/16-12 male JIC 37 flare is meticulously engineered for robust and leak-proof connections in instrumentation and process tubing systems. The double ferrule design effectively compensates for variations in tubing material hardness and wall thickness ensuring a secure leak-tight connection across diverse applications.

Duolok fittings manufactured from type 316 stainless steel per ASTM A-276 and ASTM A-479 are designed to be interchangeable with Swagelok tube fittings providing reliable performance and compatibility. Machined from close-grained 316 stainless steel forgings the shaped bodies are produced in accordance with ASTM A-182 and all components are heat code traceable with certified material test reports (CMTRs) available.

These tube fittings are rated for pressures equal to the maximum allowable working pressures of the tubing with special fittings potentially featuring different ratings. They function reliably across a wide range of operating temperatures which may impact the maximum working pressure.

Hey, will this here fitting work to connect a 3/4 inch stainless steel tube to a 1-1/16-12 male JIC flare?

Answer by: Customer Support on Sep 20, 2025, 6:15 AM

Yes sir, this stainless steel Duolok fitting is made to connect a 0.75 inch OD tube to a 1-1/16-12 male JIC 37 degree flare.

Question by: Denise P on Jan 15, 2026, 10:41 AM

Are these Duolok fittings actually interchangeable with Swagelok, or is that just marketing talk? I've got a system already built around Swagelok components and can't afford any leaks.

Answer by: Customer Support on Jan 17, 2026, 6:44 AM

Fully interchangeable. SSP engineers and quality-controls these to match Swagelok tube fittings dimension for dimension, so swapping them into an existing system isn't a gamble. The double ferrule design works the same way, compensating for differences in tubing hardness and wall thickness to give you a leak-tight seat. If your current setup runs Swagelok, these drop right in without any rework.

got 3/4 inch stainless tubing, will this fitting actually bite and seal even if the tube wall is a little different than the last batch i used?

Answer by: Customer Support on May 29, 2025, 12:15 PM

With Duolok’s double ferrule setup, the fitting is meant to handle normal variation in tubing material hardness and wall thickness and still pull up to a leak tight connection. It’s built for instrumentation and process tubing systems, and it’s rated to the maximum allowable working pressure of the tubing you’re using.
