You are watching: Can cpvc cement be used on pvc

Solvent cement is not glue. Rather it is a fast, easy installation process that supplies solvents and also resin to chemically fuse the pipe and fitting together at a molecular level, essentially producing one continuous piece the plastic. In fact, solvent cement is the just joining technique recommended because that system features like growth loops since it allows the pipeline to bend and move without breaking or weakening the joint seal.

To ensure the solvent cement is used properly throughout your procedure system, we"ve put together the complying with dos and don’ts to remember transparent the seven step involvement process.

If the detailed solvent cement environment do"s and also don"ts room followed, see exactly how reliable the joints end up being by the town hall the explode test video clip below.

CPVC Solvent Cement Welded share Burst Test


1. Cut CPVC

Do: Use devices designed because that use with plastic pipe and fittings.

Preferred plastic cut tools encompass a ratchet cutter, wheel-type plastic tube cutter, a strength saw, or a fine-toothed saw.

Do: certain the CPVC is reduced squarely by making use of a miter box.

Cutting the pipe as squarely as possible provides the maximum bonding surface ar area. The much more surface area that becomes chemically bonded, the an ext strength the joint will certainly exhibit.Don’t: usage a dull or broken cutting device blade.

2. Chamfering and also Deburring CPVC


Do: remove burrs and also filings.

Burrs and also filings deserve to prevent suitable contact between the pipe and fitting and may placed undue stress on the pipe and fitting assembly. Usage a chamfering device or file to eliminate burrs and also filings native the outside and also inside of the pipe.

Do: ar a slight bevel at the end of the pipe.

A slight bevel eases entry of the pipe into the socket and also minimizes the chance of clean everything solvent cement native the fitting. For pipe sizes 2 in. And larger, a 10 to 15° chamfer that 3/32 in. Is recommended.

3. Preparing the Fitting for Solvent Cement

Do: v a clean, dry rag, wipe any loose soil and moisture from the fitting socket and the pipeline end.

Loose soil and/or moisture can slow cure times and also reduce the joint strength. Make certain the fit is good by checking that the pipeline enters the installation socket easily 1/3 to 2/3 the the depth.

Note: If the pipe bottoms in the fitting with small interference, try a brand-new fitting.

4. Primer Application



Do: usage primer conforming to ASTM F656 and also a suitable applicator.

Primer is required to prepare the bonding area for the enhancement of cement and subsequent assembly. Use a ideal applicator, such together a dauber, swab or paintbrush, approximately fifty percent the size of the pipeline diameter.

Apply the primer to the inside of the fitting socket and also to the outiside that the pipe end. Apply a 2nd primer coating within the installation socket. Redip the applicator as regularly as necessary to certain the entire surface the both pieces is tacky.

Don"t: usage a rag to apply the primer.

5. Solvent Cement Application

Do: Use just solvent cement conforming come ASTM F493

Apply solvent cement once the pipe surface ar is tacky (not wet) indigenous primer. The joining surfaces should be penetrated and softened.

Cement have to be applied with a organic bristle brush or swab half the dimension of the pipe diameter. For pipe sizes smaller than 2 in., a dauber might be used.

Apply a heavy, even coat that cement come the external of the pipeline end, and a medium coat to the inside of the fitting socket. For pipe sizes higher than 2 in., use a 2nd coat that cement top top the pipe end.



Don’t: enable puddling of solvent cement in the fittings and pipe.

Don’t: use solvent cement near sources that heat, open up flames, or as soon as smoking.

Don’t: usage solvent cement the exceeds its shelf life or has end up being discolored or gelled.

6. Assembly


After cement application, instantly insert the pipe right into the installation socket when rotating a 1/8 come 1/2 rotate until the fitting-stop is reached. In ~ this time, the fitting should be properly aligned for installation.

The pipeline must accomplish the bottom of the installation socket. As soon as in place, the assembly must be held in place for 10 to 30 seconds to for sure initial bonding and to avoid push out.

Do: examine that a bead that cement is obvious around the pipe and also fitting juncture.

If this bead is not consistent around the socket shoulder, the may indicate that insufficient cement to be applied. In this case, the fitting must be discarded and the joint reassembled.

Wipe off any type of excess solvent cement with a rag.

Do: Use equipment for the authorized of a large diameter pipe.

For a 6 in. Or bigger diameter pipe, a pipe puller (come-a-long) is recommended to assemble the joint and also hold it in place for the initial set time without applying excess force that may damages the pipe or fitting.

This equipment should be set up prior to the begin of priming for this reason assembly have the right to happen conveniently while primer and cement space still fluid.

7. Collection and cure Times

Solvent cement set and cure times space a duty of pipe size, temperature, relative humidity, and tightness the fit.

Drying time is quicker for drier environments, smaller sized pipe sizes, high temperatures and also tighter fits.

The assembly need to be enabled to set, without any kind of stress ~ above the joint, every the time presented in the adhering to tables. Complying with the initial set period, the assembly have the right to be tackled carefully, avoiding far-reaching stresses to the joint.

Do: monitor the recommended collection times.

After a joint is assembled making use of solvent cement, it must not be disturbed because that a period of time to enable for appropriate “setting.” Recommended collection times space as follows:


Do: follow the recommended cure times.

After a joint is assembled utilizing solvent cement, the cement need to be permitted to effectively “cure” before the piping device is pressurized.

Recommended minimum cure time are shown below. This recommendations need to only offer as a guide since atmospheric conditions during surroundings will influence the curing process.

Note: High humidity and/or colder weather will require longer cure times. Typically add 50% come the recommended cure time if surroundings are humid or damp.
