Product description
The Brass ISO 7241-B Male Quick Coupler × NPTF Female is a male coupler (nipple) to the ISO 7241-B interchange, machined from brass, with an NPTF female port. ISO 7241-B (ISO-B) is the interchange used on most US and general industrial hydraulic quick couplers; parts to this interchange connect with ISO-B halves from other makers of the same size. Brass suits water, mild chemicals and corrosive surroundings better than plated steel, at a lower pressure.
Specification
- Interchange: ISO 7241-B
- Body: brass
- Port: NPTF female (Dryseal pipe thread, ASME B1.20.3)
- Temperature: −13 °F to 257 °F (−25 °C to 125 °C), as published
Pressure rating
The manufacturer publishes no pressure rating for these brass couplers. Brass ISO-B couplers rate well below steel ones of the same size; tell us the working pressure and we will confirm it.
Sizes

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.
