Hammer Unions
Sizes from ¼"
through 8" and pressures range from
500 PSI to 12,500 PSI
The sealing action of Yale Hammer
Unions is not dependent upon
metal-to-metal contact. An
elastomeric O-ring fits in a
precision-machined groove between
the metal mating parts. Forced into
sealing position at very low initial
pressure, the O-ring ensures the
utmost safety dependability and
economy despite severity of service
conditions.
