With years of extensive research and product development under our belt, the team at Oatey knows first-hand the challenges plumbers face when solvent welding, and our cements are created to meet your exact needs for any plastic pipe installation. We’ve also perfected the steps to flawless solvent welding when using our cements.
As always, the first step is to determine the pipe’s material and size, as well as the conditions of the application. Assessing these details will help ensure you choose the correct cement for your application. From there, follow these steps for successful application:
Stir or shake cement before using. If gelled, do not use. Keep container closed when not in use. Avoid eye and skin contact. Wear safety glasses with side shields and wear rubber gloves.
- Square pipe ends, chamfer and remove all dirt.
- Check dry fit of pipe and fitting. Pipe should easily go 1/3 of the way into the fitting. If pipe bottoms, it should be snug.
- Use a suitable applicator at least ½ the size of the pipe diameter. For larger size pipe systems, use a natural bristle brush or roller.
- Clean pipe and fitting with a listed primer. (Do not use primer on ABS pipe and fittings. Use Clear Cleaner only!)
- Apply liberal coat of cement to pipe to the depth of the socket; leave no uncoated surface.
- Apply a thin coat of cement to the inside of the fitting; avoid puddling of cement. Puddling can cause weakening and premature failure of pipe or fitting. Apply a second coat of cement to the pipe.
- Assemble parts QUICKLY. Cement must be fluid. If cement surface has dried, recoat both parts.
- Push pipe FULLY into fitting using a ¼ turning motion until pipe bottoms.
- Hold pipe and fitting together for 30 seconds to prevent pipe push-out – longer at low temperatures. Wipe off excess.
- Allow 15 minutes for good handling strength and 2 hours cure time at temperatures above 60 degrees Fahrenheit before pressure testing up to 180 psi. Longer cure times may be required at temperatures below 60 degrees Fahrenheit or with pipe above 3 inches. DO NOT TEST WITH AIR.
NOTE: The set up/cure time is dependent on several factors. The pipe size, socket fit, ambient temperature, relative humidity, solvent cement used and the system operating pressure should all be considered when determining set up cure times.
For special cements and chemical applications, please see specific product label instructions.
