General Uses:

High pressure air, water, steam and other high pressure, elevated temperature applications. Fitting styles include: tapered seat and washer seals ground joints, interlocking male stems, and interlocking hose menders.

Limitations:

For ASME B31.1 applications:

A. Ground joints, malleable or ductile interlocking male stems not to be used for toxic fluids or flammable gases.

B. Steel interlocking male stems limited to +412.8°C. Malleable or ducting ground joints or interlocking male stems limited to 359 psi and +232.2°C.

C. Steel or ductile ground joints or interlocking male stems limited to 204.4°C for flammable or combustible liquids. Malleable ground joints or interlocking male stems may not be suitable for flammable or combustibile fluids.

For general service applications:

A. Clamps other than interlocking style may be used, however, pressure and temperature rating charts will not apply. Generally, use of non-interlocking clamps result in similar pressure ratings as other similar shank style fittings.

B. Use of ground joints or interlocking male stems of unknown or untraceable origin are not recommended for critical applications such as toxic, flammable, combustible fluids, or cyclic conditions involving either temperature or pressure.
