“This product is amazing! I am a Sr. parts manager for a Kubota dealer and my rental department loves this product. They no longer have to get covered in oil every time they try and change the hammer or anything off our skid steers.”
— S.K., Kubota dealer Sr. Parts Manager

Quick answers

Will it fit my coupler?

Each tool is made for one coupler style and one body size, so it isn’t universal. Type the part number stamped on the metal coupler (not the numbers printed on the hose) into our Tool Finder, or measure your coupler.

Do I need the male or female tool?

For flat face couplers, trapped pressure can be in either half, so most customers get both tools. 7241-A, 7241-B and Ag/Pioneer tools already come as a male + female set.

Does oil come out?

Only a little. Turn the plunger until fluid begins to flow, then stop — the trapped pressure is gone. Keep a rag handy.

What if I order the wrong size?

Our Right Size Guarantee covers you: exchange for the correct tool, or a full refund within 30 days. No restocking fee; you cover return shipping. Email relief@relieftool.com.

How fast does it ship?

Shipping is free in the US. Orders ship the next business day by USPS Priority Mail (typically 3–5 business days).

★★★★★ Lifesaver for Hydraulic Attachments!

"I fought with hydraulic quick couplers for awhile before I learned of these. These gizmos completely eliminated the frustration of relieving the line pressure so the quick couplers can attach easily. If you have a hydraulic tractor attachment and don't have these, get them now."

— D.

Fits 3/8" 7241-B couplers only. Will NOT fit flat-face couplers. These tools are not universal — each is machined for one specific coupler.

These work great, saving time and the frustration of relieving pressure off my grapple to reattach the hydraulic hoses. I release the pressure by toggling tje 3rd function controls before detaching the hoses but if there is a temperature change such as having the attachment in the sun, it will build pressure and make it difficult to get the hoses to couple. This sure beats getting the wrenches out to break a line loose to release pressure.

This set of tools has solved the problem of struggling with hydraulic hoses that still have pressure. I wish I had found them fifteen years ago.
