Review on 🔧 Optimized Brass Shutoff Fittings by Joywayus by Chad Judex

. I used this to straddle the 3/4" heater hoses from the heater in the back of the van. There are two latches under the hood. This allows you to quickly find a solution if there is a leak in the rear of the van while maintaining roadworthiness. The fit is not good for the 3/4 inch rubber heater hose. The valve falls right out of the house without the clamp. But with a clamp it tightens enough. I'm assuming it's for 3/4" PEX or some other 3/4 standard. Not rubber tubing. Also, the ball valve isn't what I would call full bore. I forgot the size, but it was noticeably smaller as ID fittings. Maybe 1/2" or 5/8". That's not a problem for me but should be considered if one has high flow requirements. Despite these minor disappointments I give 5 stars as it's well made and probably works great in the applications it's really intended for.
