Solvent cement is not glue. Instead it is a fast, easy installation process that uses solvents and resin to chemically fuse the pipe and fitting together at a molecular level, essentially creating one continuous piece of plastic. In fact, solvent cement is the only joining method recommended for system features like expansion loops because it allows the pipe to bend and move without breaking or weakening the joint seal.
If the provided solvent cement installation do's and don'ts are followed, see how reliable the joints become by watching the burst test video below. Preferred plastic cutting tools include a ratchet cutter, wheel-type plastic tubing cutter, a power saw, or a fine-toothed saw. Cutting the pipe as squarely as possible provides the maximum bonding surface area. The more surface area that becomes chemically bonded, the more strength the joint will exhibit.
Burrs and filings can prevent proper contact between the pipe and fitting and may put undue stress on the pipe and fitting assembly. Use a chamfering tool or file to remove burrs and filings from the outside and inside of the pipe. A slight bevel eases entry of the pipe into the socket and minimizes the chance of wiping solvent cement from the fitting.
For pipe sizes 2 in. Do: With a clean, dry rag, wipe any loose soil and moisture from the fitting socket and the pipe end. Primer is needed to prepare the bonding area for the addition of cement and subsequent assembly. Use a proper applicator, such as a dauber, swab or paintbrush, approximately half the size of the pipe diameter. Apply the primer to the inside of the fitting socket and to the outiside of the pipe end.
A: Solvent welding is a chemical process that uses a primer, or the cement itself, to soften the surface of plastic pipe and fittings in order to weld, or fuse them together. This requires a tight, or interference fit. The solids contained in the solvent cement will then fill the gap between the pipe and fitting.
Glue such as PVC glue, on the other hand, is only a bonding cement and will not work with an interference fit. A: Primers pre-soften the surface of the pipe and fitting before the solvent cement is applied so that maximum fusion can take place.
A: To remove grease, dirt, and foreign matter from the surface of the pipe and fitting prior to application of the primer and cement. A: The Set Time is the amount of time the joint is to be left undisturbed before handling.
The Cure Time is the amount of time it takes the joint to be completely set and ready for pressure to be applied. Low VOC products contribute to cleaner air. A: Yes. However, it is recommended to use the correct WeldOn primer and PVC solvent adhesive for the particular application. At colder temperatures it is safer to double the curing times. Oatey 8 oz. Including the Dauber handle for application. The glue itself is not very strong.
Glue is really a solvent for the plastic tube. It can harden under water. Always remember to never use a primer on or with ABS products. PVC cement glue and primer are used to soften the pipes and weld the pipe sections together. Polyvinyl chloride quickly holds pipe sections in place in a process known as solvent welding.
