How to Disconnect Two Pipes with a NPT Threaded fitting | 3 Steps

In order for your household plumbing system to function optimally, you need good end-to-end connectivity. This is why standard use pipes, like NPT pipe connections, are so important. By using NPT pipe connections, you’re ensured better communication between different parts of the plumbing system, making it easier to solve problems and troubleshoot issues. If you’re not using NPT pipe connections in your plumbing system, now is the time to do so! By following these simple steps, you’ll have better connectivity in no time.

 

Remove the cap of the first pipe by unscrewing it from the stem 

Removing the caps of pipe can be a tedious and time-consuming task, but with a little preparation it can be a breeze. First, sprayPaint or degreaser around the entrance hole(s) on eachside of eachpipe (depending on the brand) and screw them back into place with new screws. If there are several caps and theyre all tight, use a wrench or pliers to loosen them one at a time before removing them completely. Be careful not to touch any sharp edges on either side of the pipe as you do this! Once all the caps are off, sprayPaint or degreaser around the entrance hole(s) on eachside of eachpipe (depending on the brand) and screw them back into place with new screws. Thats it!

 

Fit the end of the NPT into the thread on the cap of the first pipe, making sure that the flange on the NPT is facing down 

When it comes to plumbing, making sure everything is snug and sealed is key. Thats why its important to follow these simple steps when fitting pipes together: Fit one locknut around each pipe, tighten bolts until locksnut CPC are fully engaged, and make sure that the flange on each pipe is facing down. After that, thread the NPT end of the first pipe onto the thread on the cap of the second pipe. Thats all there is to it!

 

Screw on the cap to tighten 

Drilling and screwing can be a dangerous business, so its important to use the right tools for the job. For screws in hard-to-reach areas, use a socket wrench. Make sure to screw on the cap to tighten the head of the drill bit, as this will help prevent fingers from getting trapped between screw and housing. Avoid getting the bit loose over time by always keeping it tightened with a Phillips screwdriver. And lastly, dont forget to wear safety goggles when drilling and screwing to avoid any potential injuries.
