Gorilla Glue can be used from 32 to 140° F. The amazing thing about this glue is that it will work on all kinds of pipes, from the smallest PVC pipe up to a 6″ diameter pipe. The glue itself is as strong as the pipe, ensuring a secure, durable connection.

Traditionally, connecting PEX to copper depends on the end of the pipe you’re connecting to. If the pipe is not threaded, you may use a male or female slip adapter. This method requires soldering the adapter to the copper pipe before fitting the PEX to the other end and securing with a crimp.

Copper is a highly-conductive, corrosion resistant and ductile metal which is easily bonded by epoxies, acrylics or cyanoacrylates offered by most glue companies. Loctite, gorilla glue or super glue will all work as they are basically all same glue.

Connecting copper and PVC requires the right glue. Metal and plastic don’t bond well. You can join the two with a specially formulated polypropylene-polyethylene adhesive made to work with hard-to-bond materials, a good prep job and some time to let the glue cure.

Cyanoacrylate adhesives or instant adhesives are ideal for bonding copper. The highest strength bonds are created with methyl cyanoacrylates such as the original Permabond 910.

Gorilla Glue Waterproof Patch and Seal Tape can fix a leaking gutter in a few minutes. Gorilla Waterproof Patch & Seal Tape can instantly seal out water, air & moisture.

The solvent cement, applied to both of the pieces being joined, temporarily melts a thin layer of PVC, which resolidifies in the seconds after the pieces are put together and forms a seamless, waterproof, airtight seal.

As answered before, PVC cement is not a glue but a solvent, melting the PVC so you can “cold weld” it without using heat. However, contact cement, hot glue and super glue all have reasonable to good adhesion on PVC, so they can be used to glue PVC if the application is not too demanding.

Some will tell you that primer is not necessary to create strong PVC joints. While you may be able to create strong joints without it, primer is an important part in making sure your joints are as strong as they possibly can be. We recommend you use primer on any joints that will have liquid media passing through them.

After joining the pipes you must hold them together for 30 seconds until the plastic hardens or they can slip apart. It takes another 15 minutes for the joint to harden to a point at which it can withstand water pressure and two hours to fully cure.

In know that PVC should be chamfered and even lightly sanded before gluing for better insertion on the fitting (and probably some other reason). What about CPVC, a manual told me to just cut, apply glue and insert the pipe into the fitting keeping pressure. No sanding, no chamfering and no wiping with primer.

After you joining the pipes you need to hold them together for at least 30 seconds so the cement can harden. It will take another 15 minutes for the joint to set to the point that it can withstand water pressure and another two hours to cure fully.

No – PVC Primer does not need to ‘dry’ before use – in fact, it needs to be wet to do it’s job and not impede the cement – remember, plumbers in a hurry use this daily and aren’t sitting around waiting for the primer to dry before grabbing the cement.

Adding too much cement to a pipe and joint does not have any derogatory impact on the sealing of the joint, however excess glue which comes out the joint, if left in contact with the plastic, can, over time, weaken it, and reduce it’s pressure rating. So, if you’re a slapper, wipe the excess off!

PVC pipes and joint fittings are typically glued together with PVC solvent glue. But if you have a leak in a PVC drain pipe, often you can repair it temporarily until there’s time for a permanent fix. Drain pipes are not pressurized, which makes temporary repairs relatively effective.

Use pipe thread tape, sometimes called “Teflon” or “Plumber’s” pipe, to fix leaking pipe joints. Use silicone, sometimes called “self-amalgamating,” “self-fusing,” or “leak repair” tape, to fix hairline cracks or other non-joint pipe leaks. In fact, professional plumbers might use tape effectively all the time.

Epoxy. Repair epoxy is putty or viscous liquid that can be used to repair pipe leaks on PVC and its joints. To repair your pipe or joint using epoxy, first clean and dry the damaged area, ensuring water can’t reach the affected area.

A: No, Flex Seal is not made to withstand extreme heat or pressure.

Flex Seal, can work on most surfaces and is promoted for the use on windows, roofs, pipes, gutters, and cement fixtures. There are cautions about where and when to use this spray. Since it is spraying a coating of flexible rubber it’s advised not use the product anywhere except for well-ventilated areas.

Plumber’s putty may only be used to prevent or stop leaks in specific areas. It shouldn’t be used interchangeably with other products such as caulk or tape. Plumber’s putty should be avoided when working with granite and marble since it may stain those types of surfaces.
