Q:Can this be welded? I am trying to make use of pipe and caps for the bottom of a workbench that needs to be easily broken down
by|Jun 12, 2023
1 Answer
Answer This Question

A:  Hello, this fitting is designed to thread onto black steel plumbing threaded pipe labeled as 1/2-in diameter. We recommend checking local codes for what is recommended for any application where threading is not feasible to ensure all aspects of your project are accounted for. We hope this helps with your project.

        Q:replace?
        by|Oct 9, 2015
        1 Answer
        Answer This Question

        A:  Use two pipe wrenches, one to hold the pipe and one to remove the cap. Caps are generally righty tighty / lefty loosey. If pipe needs replacing you can remove that and replace it with a new nipple or pipe, threaded on both ends.

          It did not fit properly and I needed something to completely seal. Was told this would work to seal off gas line for a dryer. Had to purchase a different product.

                    Bad workmanship
                    These come coated with dark oil inside a sealed cellophane wrapper with printing on it so you cannot examine closely before buying. The threads on mine were machined off-axis, so when the cap is threaded onto a pipe, it wobbles around and cannot be screwed on straight.
