HAMMER UNION SEALS

Hammer unions also referred to as wing unions are designed to be quick connect / disconnect couplings that are typically used in temporary flow lines or in equipment that will be periodically disassembled. the hammer union seal is relatively large elastomeric annular seal that is rectangular in cross section.

The seal is "actuated " when it is compressed between the coupling components when they are cinched up. the hammer union seal is exposed to the gases and fluids that flow through the coupling making the choice of the optimum rubber compound critical . We manufacture hammer union seals , from sizes 1" up to 10" , in a number of compounds including RGD resistant compound.
