“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
Female tool going onto a real coupler — push it on, tighten, relieve.

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).
