All pipe surfaces should be thoroughly cleaned with pipe cleaner. The cleaner is formulated to remove surface dirt and any oil or grease that exists on the pipe from the manufacturing process. Primer/cleaner and primer contain more aggressive solvents and will soften the pipe surface to allow the solvent cement to penetrate more effectively. Primer is often required by plumbing code and sometimes a purple colored primer (purple primer) is needed.

Pipe dope is an industry slang term for thread sealant. It lubricates and seals when it is brushed on to pipe threads where two pipes are joined.
While we recommend that solvent cement be applied between 40 and 100 degrees Fahrenheit, weather conditions may not make this feasible. A strong solvent welded joint can be made at temperatures below freezing as long as the solvent cement is fluid, cure times are extended and other handling precautions are followed.
These are three different types of plastic pipe used in plumbing applications. PVC is Poly(Vinyl) Chloride, CPVC is Chlorinated Poly(Vinyl) Chloride and ABS is Acrylonitrile-Butadiene-Styrene. PVC and ABS pipe are normally used for drain, waste and vent (DWV) systems, while CPVC is used for water distribution systems. It is important to choose the correct solvent cement or pipe glue based on the type of plastic pipe being used.
The cure time is dependent on several factors. The pipe size, socket fit, ambient temperature, relative humidity, solvent cements or pipe glue used and the system operating pressure should all be considered when determining cure times. The following chart can be used as a guideline to determine joint cure time: Pipe size movement of joint 10% of rated pipe pressure

Each of our solvent cements (excluding gallon sizes) have a dauber included in the can. This dauber can be used to apply cement to pipe sizes up to 3". If the size is greater than 3" in diameter, we recommend the applicator (brush, roller, etc.) size to be 1/2 the pipe diameter.
We do not recommend attempting to thin solvent cements. The solvents in the can will evaporate if left open for extended periods of time, causing the product to thicken or gel. Do not use gelled or thickened cements on plastic pipe.
It is important to carefully select the proper solvent cement for your application. Oatey manufactures several varieties of solvent cement. PVC cements should be used for PVC pipe and fittings, CPVC cements should be used for CPVC pipe and fittings and ABS cement should be used for ABS pipe and fittings. We also manufacture specialty cements such as transition, flexible and all-purpose cements.
Because the primers will soften the pipe surface, it is important to apply solvent cement to the pipe and fittings while the primer is still wet to achieve maximum bond strength.
The pigments or dyes in Oatey Purple Primer and Oatey Purple Primer/Cleaner are permanent. Depending on the type of material stained, its porosity and the length of time the stain has set, it may be possible to remove or lighten the stain. We recommend blotting a clean, dry towel with Oatey Clear Cleaner to attempt to remove the stain. It may not be possible to remove the colorant from particular fabrics or surfaces. The finish and/or color of certain fabrics or materials may be dulled or discolored when in contact with solvents in Oatey Clear Cleaner. You may want to try the cleaner on an inconspicuous spot before using on the stained area. Please use our purple primers and colored cements with caution.
Yes, Oatey Flashings are rated for use on Type B vents.
Yes, Oatey manufactures a roof flashing that can be used on roofs with 10 to 60 degrees pitch. Oatey High Rise No-Calk Flashings are products #11930 and #11931.
Yes, Oatey carries MasterFlash, which can conform to most roof profiles.
The box is made of high-impact Polystyrene and can be solvent welded with either ABS or PVC cement. A PVC cement should be used when using PVC pipe and an ABS cement should be used when using ABS pipe.
