Replacing an existing coupling?

This coupler is dimensionally interchangeable with Eaton 5400, and with Mobile A/C OEM refrigerant couplers. If you are matching an existing fleet, quote the coupling you are replacing on the RFQ and we will confirm the mating half before you order.

How to order

Confirm the coupling half (male / female / complete set / dust cap), body size, port thread type and size, seal compound and body material. Indus quotes with material certification on request, and air-freight or sea-freight to the UAE and wider GCC. Standard lead time 14 days from order; stocked configurations ship the same week.
