Tighter than a drum - this check valve works great. And, it pays for itself. Run time on the vacuum pump dropped to way low usage while this check valve protects the vacuum level for the automatic vacuum switch to do its job.

Review by Russell Davis
The check valve works flawlessly. I built an onboard air system for my GMC truck and the valve has performed above expectations.
Solid construction, durable, and reliable - qualities usually lost in modestly priced fittings can be expected from this product....recommended this item and this seller to others seeking this product.
In all - very satisfied with product, price, seller, service - all around - GREAT.
