INSTRUCTIONS FOR KWIK-COUPLER™
CHARGING HOSE
U.S. Patent No. 4,458,719
APPLICATION INFORMATION
The Kwik-Coupler™ hose set is intended for use with refrigeration air conditioning service manifold
high (red), low (blue), and accessory (yellow) side service fittings. Conventional threaded connecting is
converted to push-pull operation which is faster, easier, and positive sealing at all times. The high and
low side Kwik-Couplers™ are intended for use when connecting to core valve-type fittings. Valve cores
are depressed automatically without adjustments or loss of refrigerant. The accessory side
Kwik-Coupler™ is intended for use when connecting to equipment, such as a tank or vacuum pump,
that does not utilize core valve-type fittings. The automatic shutoff valve in the hose is opened when the
Kwik-Coupler™ is engaged.
An automatic shutoff valve retains refrigerant pressure in a disconnected hose. This feature permits
transferring the high side hose refrigerant through the service manifold into the low side, thereby
eliminating waste and hazardous high pressure discharge. Hoses can also be stored under low side
pressure to prevent contamination, if desired.
Imperial Kwik Coupler Charging Hose can be obtained with SAE 1/4” connections, or with female coupler for
connecting to automotive air conditioning high side service fittings, utilizing a smaller 3/8-24 thread.
WARNING -- DO NOT ALLOW ANY REFRIGERANT CAN, CONNECTED
FOR CHARGING TO BE EXPOSED TO SYSTEM HIGH SIDE
PRESSURE - CAN EXPLOSION COULD RESULT.
Operating Instructions
1. No adjustment of valve core depressor is required.
2. Thread female coupler onto core valve service fitting - use finger tight torque.
3. To connect, engage couplers and push inward until spring loaded clip on male coupler engages slot on female
coupler. On systems with core valve-type fittings engagement is complete, and the manifold gauge should read
system pressure. On accessory equipment, such as storage tanks, that utilizes manual valves, the valves
should be opened after engaging the Kwik-Couplers™. The manifold gauge will then read system pressure.
4. Before disconnecting, the manual valves on accessory equipment should be closed. To disconnect
Kwik-Couplers™, depress spring loaded clip on male member and pull outward. An automatic shutoff in the
male coupler member will maintain the disconnected hose under pressure. High pressure can be transferred
through the manifold into the low side of the system. Hoses can be stored under low pressure or discharged
into an approved container.
DO NOT DISCHARGE REFRIGERANT INTO ATMOSPHERE UNDER PENALTY OF LAW.
