How long pipe dope

Not that the start up time changed. Edited 1 times. If I can get to the shutoff valve fast enough, I wait about 30 seconds. Pipe dope does NOT have a "cure time". Once the joint is completed the dope has sealed if, if it is ever going to.

It works! No leak. However, one of the hose bibs I turned past vertical on the last turn to tighten. I remember reading here that you never unwind, so I had to turn it one more revolution, it was so tight I thought it was going to snap off. I am not sure I will be able to ever loosen it back out. There is no "perfect" pipe thread. The dope is to lubricate, but also to fill the minute voids that always occur when two pieces are threaded together. As already mentioned, cure time for normal pipe dope is 0 secs.

For the past decade, I have been using Loctite pipe dope. It is like a very mild threadlocker and sets up over a few hours. It will seal against normal pressures instantly but will seal higher pressures if given curing time. I highly recommend this thread sealer. Loctite doesn't harden much, so it is possible to take apart joints without too much force. Done it many times. That results in a seal that adheres strongly to both metal and plastic pipes to prevent leaking.

Pipe joint compound is easy to find, fairly simple to use, and inexpensive. It works with all types of pipe and fitting materials, and it produces a strong seal. Pipe dope is generally stronger seal than Teflon tape, which is why plumbers and other professionals use it rather than tape for seals that are permanent. If you have a plumbing job that needs to be done in your home, you have a choice of what type of pipe sealant to use.

You want to make sure that you have an airtight seal and that there are no leaks in the pipes or fittings. If you can't find what you need, visit our customer support section. All Rights Reserved.

For DOPE, is it generally 1 year or as long as the consistency is fine? Last edited by a moderator: Mar 17, When the consistency is too thick, just add some mineral oil, or pipe thread cutting oil , and stir.

As my did used to say, the first half of the can goes fast. The second half lasts forever, just keep adding oil. Joined: Aug 13, Location: California. You can buy pipe dope in a small tube.
