Sizes and part numbers
The Sizes & Part Numbers tab lists every Parker part number with its connection. Ratings vary by size and connection — check the row for the part you order.
Matching halves
Quick couplings only seal and flow at their rating when both halves come from the same interchange profile. Quote the part number of the mating half too, or tell us what it must connect to, and we will confirm the match before supply.
How to order
Quote the Parker part number. Price and lead time are confirmed with the quotation.

Description — What this part number is, as the manufacturer lists it. Type — Which part of the coupling this is: coupler (female half), nipple (male half), complete set, dust cap or adapter. Body size — Nominal body size of the coupling, which sets which halves mate. Rated pressure — Rated working pressure, as the manufacturer publishes it. A circuit is limited by its lowest-rated component. Rated flow — Rated flow in US gallons per minute, as the manufacturer publishes it. A circuit is limited by its lowest-rated component. Ask us for the dimension drawing if you need it stamped.
Pressure, flow, speed, torque and load figures are the manufacturer’s published ratings for that part number. A circuit is limited by its lowest-rated component, so check them against the hose, fittings and valves it connects to.

Trapped pressure: why the coupler will not connect, and how to release it safely
An attachment left in the sun all morning can build enough pressure in a disconnected line to make a coupler impossible to push home. Forcing it is the part that hurts people.

Failure analysis
What splits a female coupler half
A cracked female coupler body is not a manufacturing defect and it is not bad luck. It is almost always one of three things, and two of them are avoidable for nothing.

Tractors and implements: the couplers are older than the machine
Agricultural hydraulics run on a coupler standard that has barely changed in decades, which is why a 1990s implement still connects to a new tractor — and why grit gets into everything.
