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
