Frequently Asked Questions

What is a quick-disconnect coupler?

It is a reusable connection that allows a hose or tool to be connected and disconnected without unthreading the fitting.

What does interchange style mean?

It describes the plug and coupler profile. Matching the correct interchange is essential for proper connection and sealing.

Can different interchange styles be connected?

Not normally. Universal couplers are designed to accept multiple specified plug profiles, but standard couplers should be matched to their intended interchange.

How do I choose the correct body size?

Select body size and port size based on required flow, tool demand and hose diameter.

Do quick couplers cause pressure drop?

Yes. Internal passages and valving create some restriction, so high-flow applications should use an appropriately sized coupler.

What materials are available?

Material depends on the series and may include brass, steel or composite bodies.

When should a coupler be replaced?

Replace it if it leaks, will not lock securely, has damaged seals or shows excessive wear.

How do I select the correct coupler?

Confirm interchange, body size, thread, flow, pressure, media and environmental conditions.
