PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene) cement fittings are components used to connect compatible plastic pipesin order to convey fluids or chemicals.How do PVC and ABS cement fittings work?PVC and ABS cement fittings are connected through solvent welding. A substance called solvent cement is applied to the pipe before it is slid into the fitting. A chemical reaction between the solvent cement and the PVC or ABS fitting causes the two touching surfaces to melt and fuse together, in much the same way that metal is welded.PVC and ABS cement fittings are often used in, for example, the water treatment, ship building and chemical processing industries. Depending on the type, they can connect straight pipe or tubing sections, adapt to different sizes or shapes and regulate or measure fluid flow. They tend to be very robust and resistant to impact, corrosion and chemicals.Types of PVC and ABS cement fittingsPVC and ABS threaded fittings come in various styles depending on your needs, for example couplings, reducers, elbows, nipples and adaptors.
