Stainless Steel Duolok Tube Fitting, 0.75 Inch Tube OD Plug

Description & Features

SSP Duolok Stainless Tube Fittings deliver reliable leak-proof connections in instrumentation and process tubing systems. The double ferrule design accommodates variations in tubing materials hardness and wall thickness to ensure leak-tight connections across numerous applications.

Duolok fittings including the Stainless Steel Duolok Tube Fitting 0.75 Inch Tube OD Plug offer gageability to verify sufficient pull-up during initial installation. All components are heat code traceable and certified material test reports (CMTRs) are available guaranteeing quality from type 316 stainless steel in compliance with ASTM standards.

Interchangeability is a key feature as these fittings are entirely compatible with Swagelok brand tube fittings. Duolok tube fittings are pressure-rated to match the maximum allowable working pressures of the recommended stainless steel tubing. However specific designs may carry different ratings.

These fittings are built to function reliably across a wide range of temperatures. For elevated temperature applications additional assistance may be required to ensure optimal performance. Always refer to safety information for proper selection and use of tubing and fittings.
