## Description

Mess Stopper Hydraulic Oil Service Plugs are most commonly used to prevent oil leaks when servicing equipment and machinery. The plugs also keep your equipment and oil clean during servicing. Its gradual taper allows it to fit a variety of hole sizes so it eliminates the need to keep and store the right size plugs and caps.

Review: Great addition for brake jobs - Small size is excellent for sealing flared brake line fitting
Review: Great - Had to replace the hydraulic oil cooler on an excavator, one of the medium ones held the entire contents of the reservoir while upside down for 3 days, my only regret is not buying them sooner.

### ⭐⭐⭐⭐⭐ Great
*by B***8 on August 23, 2024*

Had to replace the hydraulic oil cooler on an excavator, one of the medium ones held the entire contents of the reservoir while upside down for 3 days, my only regret is not buying them sooner.

### ⭐⭐⭐⭐⭐ Expensive Since Only Needed Two to Plug 2 Lines, But Did The Job
*by N***E on July 27, 2024*

I need 2 to plug the brakes lines in a tight area. It worked well for my one-off needs and was the only solution I found after an extensive search.
