Are your quick couplings compatible with the original SWACO Super Choke?
Yes. Couplings 20-10-040 and 20-10-041 are manufactured as replacements for the original Super Choke connections. Provide the part number and we will confirm compatibility.
What thread do these quick couplings use?
Both couplings are 1/4 in NPT: part 20-10-040 is the female coupling and part 20-10-041 is the male coupling, so they can be supplied as a matched pair.
