4 Inch ABS Double Wye, ABS Construction. This particular fitting is a Double Wye Fitting for ABS Pipe applications and has a solid ABS (Acrylonitrile Butadiene Styrene) construction. It measures 4 inches on all connections creating the four inlets and outlets. A Double Wye fitting is used in a piping system and has two sloping (45 Degree) center connections which make it easy to transport waste through a stack, eliminating the possibility of clogging. In order to properly install this fitting, ABS cement is required to secure the wye fitting to the existing pipe and also to create a strong connection for other pipes and fittings in the system. Unlike PVC, ASB fittings and pipe do not need a “primer” in order to soften the pipe and create a solvent weld. This will save you time as you fix or construct your plumbing system. ABS pipes and fittings are used in a wide variety of DWV (Drain, Waste and Vent) applications. It can also be installed above or below ground due to its ability to be resistant to most acids, salts and alkalis.
