Special Purpose – Exhaust - Steel
E-z-mate Series Industrial Interchange
Features
• Parker's E-z-mate is an exhaust type coupler that is designed
to exhaust air pressure prior to the disconnection process.
• The valve sleeve acts as an integral shut-off valve that
allows connection and disconnection at zero pressure.
When the sleeve is moved to shut off air flow, it
automatically vents downstream allowing for disconnection
at zero pressure and eliminating the risk of “hose whip.”
• Meets ISO 4414 requirements for a controlled pressure
release system.
• Built-in sleeve-lok mechanically locks the valve sleeve to
help prevent accidental disconnects.
• Proven ball locking mechanism evenly distributes 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.
• O-ring interface seal assures “bubble tight” seal and long
service life.
• E-z-mate Series couplers use industrial interchange nipples.
• Brass versions available. Contact the division for availability.
Operation
Parker E-z-mate couplings combine push-to-connect,
exhaust-style action with a self-locking valve sleeve to guard
against accidental disconnection. Simply follow the direction
of the On-Off arrow stamped on the valve sleeve. It’s that easy.
To connect, push the nipple into the coupler. The black locking
sleeve automatically slides forward securely locking the nipple
in place. No air is allowed to flow through the coupling at this
point. The valve sleeve is then rotated clockwise (when
viewed from the coupler port end) to open flow and
automatically engage the sleeve-lock mechanism.
To disconnect, rotate the valve sleeve counter clockwise
(when viewed from the coupler end). The flow of air through
the coupling will be shut off and all downstream air is vented
to the atmosphere. The locking sleeve may now be retracted
and the nipple removed. Lubricate sleeve as part of periodic
maintenance to coupler.
