Connect varying sizes of hose and fittings with ease, all Chicago type hose couplings interchange through 1′. Chicago Couplings 1″ and under have a 2-lug head design that mates with any 2-lug coupling regardless of hose or thread diameter. All couplings over 1″ have a 4-lug design that interchanges between all 4 lug sizes. If you have a coupling larger than 1″ with a 2-lug design, it is probably a sandblast coupling or an interchange from overseas.

Split one larger hose into two smaller diameter lines with a Chicago Y coupling. Dead-end a line with a Chicago coupling blank end cap. Need to branch off from a custom manifold ? Send us a message, we love a good hose and coupling challenge. We look forward to hearing from you.
