Component Part Features
1. Precision machining, hardened wear points* and solid bar
stock construction provide long life even in rugged
applications.
2. Tubular valve with large flow passages delivers high flow
with minimum pressure drop for efficient performance. The
tubular design provides 360° support for both the valve
seal and the mating nipple for long service life.
3. Precision molded seals form a “bubble tight” seal for
reliable operation within rated working pressures. Standard
seal material is Nitrile. Ethylene Propylene, Fluorocarbon
and Neoprene are available as options. See the Coupling
Selection and Ordering Guide in the front of the Pneumatic
Section of the catalog.
4. Proven ball locking mechanism with large numbers of
hardened steel or stainless steel locking balls evenly
distribute the load to resist wear and provide positive
connections. The ball locking mechanism also provides
accurate alignment and allows a swiveling action to reduce
hose torque.
5. Integral sleeve guard protects the sleeve and resists
accidental disconnects by allowing the coupling to ride over
obstructions without the sleeve being retracted.
6. Knurling on the sleeve provides a gripping surface for ease
of operation.
7. Wide range of end configurations are available to meet
specific needs. Parker push-to-connect type couplings are
available with male pipe thread, female pipe thread,
standard hose barb, and Push-Lok hose barb**.
8. Parker 20, 30, HF, and E-z-mate Series couplings mate
with industrial interchange design nipples. See Table of
Contents for additional specifications.
9. Push-to-connect design permits one-handed connection
when the coupler half is rigidly mounted.
* steel nipples only
** Push-Lok hose barbs are designed for use with Parker Push-Lok hose and
do not require clamps.
