Replacing an existing coupling?
This coupler is dimensionally interchangeable with Eaton FD48, Parker Bruning SM-250, and with Parker Bruning SM-250. 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.
Companion products
Indus also supplies the matching dust caps, dust plugs and seal repair kits for this series — add them to the same RFQ. For a hose assembly terminated with this coupler, request a complete assembly quote and we will supply it tested at 1.5× working pressure with a witness-test certificate.

Trapped pressure: why the coupler will not connect, and how to release it safely
An attachment left in the sun all morning can build enough pressure in a disconnected line to make a coupler impossible to push home. Forcing it is the part that hurts people.

What splits a female coupler half
A cracked female coupler body is not a manufacturing defect and it is not bad luck. It is almost always one of three things, and two of them are avoidable for nothing.

Tractors and implements: the couplers are older than the machine
Agricultural hydraulics run on a coupler standard that has barely changed in decades, which is why a 1990s implement still connects to a new tractor — and why grit gets into everything.
