Coupler, , SPX HOSE HALF COUPLER-3/8

Description & Features

Rated for 10,000 psi service, this coupler is designed for use with hydraulic jacks, cylinders, and related high-pressure equipment. The SPX Hose Half Coupler-3/8 is a threaded union-type fitting that allows cylinders or hoses to be interchanged quickly, with each half valved by a precision ball for reliable shutoff when disconnected. Separation from the pump is possible at 0 psi with minimal oil loss.

The flush-face design allows both coupler ends to be cleaned before connection, reducing contamination risk. A push-to-connect dry-break mechanism prevents oil spillage during coupling, and a locking collar guards against accidental disconnection. High oil flow capacity makes this fitting well-suited for demanding high-pressure hydraulic circuits. Catalog number C1JN30, supplied under the Hydraulic Tech Usa Llc (Spx) brand.

Question by: Marvin M on Jul 4, 2025, 12:47 PM

Will this coupler work with any standard 3/8" hydraulic hose?

Answer by: Customer Support on Jul 6, 2025, 7:48 AM

This coupler is designed for use with hydraulic jacks, cylinders, and related high-pressure equipment operating up to 10,000 psi.

Question by: Vince M on May 11, 2025, 12:37 PM

does this coupler work for swapping out cylinders on a 10,000 psi hydraulic setup, or is it only meant for lower pressure stuff

Answer by: Customer Support on May 13, 2025, 9:28 AM

Full 10,000 psi operation is what this fitting was built around. It uses a threaded union-type connection, so swapping cylinders in and out is quick and straightforward. Each half has a precision ball valve that shuts off tight when the coupler is separated, and you can break it from the pump at zero pressure with minimal oil loss. Good fit for high-pressure jack and cylinder work.

Question by: Joyce G on Jul 22, 2025, 7:25 PM

trying to swap cylinders around on my 10,000 psi setup, is this the kind of coupler that lets you change hoses quick without making a mess

Answer by: Customer Support on Jul 24, 2025, 6:08 AM

For swapping cylinders or hoses fast, it uses a threaded union style so you can interchange components in seconds, and the push-to-connect dry-break setup is meant to prevent oil spillage during coupling.
