1" Bulkhead ABS Threaded x Threaded NPT Standard 2-Pair (4-Pack) NBR Rubber Gasket

Works well on my 1000 liter water tank. The spouts for the value was in getting 4 as I have other tanks that I needed this on too.

Hasn’t used yet, but they do fit for the project I purchased them for.

I bought one of these from another retailer and when i installed it the product broke. This is made of stronger plastic than other retailers products. I would recommend this product.

Worked great and threads were in good condition. The gasket works pretty well, but I needed silicone to stop all leaks.

1 out of 4 split at the threads and leaked until it catastrophically failed

Fit as it should straight from the package. The threads were smooth too.

Work great and much cheeper than buying local

Busted when trying to install the 1” THREAD pvc and the bulkheads broke. Some have what’s called flash inside which is where the plastic injection molds leaked an additional amount of plastic, who ever was running the machine didn’t catch this in time. Or at least try to change the runner or carve out the flashing before it hardens as it cools
