Hose Couplings — Camlock First, Specified Against the Hose

Home / Hose Couplings

The couplings line

Couplings are where hose systems leak, whip and fail — the joint concentrates the stresses the straight run never sees. They are also where mixed sourcing carries a specific risk: a camlock bought from one catalogue and a hose from another can share a nominal size and still seat badly, because tolerances, tail profiles and gasket materials differ. The company's catalogue lists a dedicated couplings line — camlock couplings, flanges, air hose couplings and clamps — alongside its hose families. The camlock range is the first of the four coupling categories the catalogue lists.

Couplings can be raised in the same enquiry as the hose: give the hose's actual inside diameter and wall and state the mating standard at the other end — pump outlet, flange face, threaded port or another camlock half — and the coupling size for this order is confirmed in the quotation. A coupling quotation that knows both sides of the joint is specified against the real pairing; a coupling bought by nominal size alone is specified against a guess.

The lines in this range

Those are the four coupling categories the catalogue lists. The table deliberately does not assign them to hose families: which coupling serves which hose in your order — family, bore, tail fit and the mating standard at the other end — is a pairing confirmed per enquiry in the quotation, not a pairing this page asserts in advance.

Camlock — the cam-and-groove quick coupling — joins and breaks by hand, with no tools. The blog's camlock types and sizes guide explains the standard type letters (the adapter and coupler halves, dust caps and plugs) and the sizing logic in full, including the gasket material question for your medium. Flanges are the fittings in the same list. Air couplings follow the pneumatic standards of your market, which is why they are confirmed per enquiry rather than tabulated here.

Sizing, gaskets and the mistakes that cost a season

Three specification points are confirmed for a coupling order. First, the hose inside diameter and wall thickness go into the enquiry, and the coupling size and tail for this order are confirmed in the quotation. Second, gasket material: the gasket for your medium is a specification to settle in the enquiry — name the medium and temperature and have the compound confirmed in the quotation, because a gasket is a small part that ruins an expensive week when it swells against the wrong medium. Third, working pressure of the joint: a coupling set is rated as a joint with its hose and clamp, not as a metal part alone, so state the system pressure and let the quotation confirm the combination. All three points fit in one line of an enquiry each, and the form below gives you the fields for them.

For distributors, the practical facts are these: hoses wear at the ends, gaskets perish, and camlock halves walk away from sites. Couplings can be programmed as a standing line with your hose orders, rather than handled as emergency purchases. State your expected ratio of sets per hose length in the enquiry, and ask for the offer to be structured on that ratio in the quotation.

Which camlock types should a layflat buyer start with?

Start from the application rather than a fixed set: which hose each coupling has to join, which tail profile and size that joint needs, and which standard the mating half follows are questions the enquiry itself has to settle, and whether a given pairing is supplied for your order is confirmed in the quotation. The blog guide to camlock types and sizes decodes the type letters so you can name what you are asking for; dust caps and plugs for open ends in storage belong in the same conversation.

Can you supply couplings without hose?

Yes — the couplings line is a catalogue line in its own right. State the hose it must fit (family, inside diameter, wall type) and the mating standard, so the tail and gasket are specified against your hose, not a nominal guess.

Do you publish coupling sizes and prices here?

Couplings are quoted per size, material and quantity in the enquiry — state the hose bore and the coupling type you need, and the quotation confirms whether that pairing is offered and which sizes are available for it. A generic table would misstate more than it informs, because material and gasket choices move both size availability and price.
