    Flame-Retardant Drain, Waste, and Vent Polypropylene Pipe Fittings for Chemicals

    Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies. All meet UL and ASTM standards for flame retardance and self-extinguishment in the case of fire. They also meet strict ASTM specifications and testing requirements for material quality and product dimensions. They’re compatible with Orion Blueline No-Hub and Orion Rionfuse chemical waste pipe and pipe fittings.
    Either a clamp connector or electrofusion connector is required to connect grooved ends on adapters to pipe or to another fitting with a grooved end. Clamp connectors can be easily taken apart as needed for maintenance. Grooving tools (sold separately) prepare ungrooved ends for clamping. Electrofusion connectors create a stronger, more permanent connection than clamp connectors. Use electrofusion tools (sold separately) to weld these fittings in place.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Grooving Tool

    Fittings that swivel until tightened connect an NPT-threaded sink drain to a 270° bend fitting. They’re also known as sink drain tailpieces. They rotate for easy installation and have a quick-access nut that lets you perform maintenance without removing the fitting from your line. Cut them to length.
    Adapters with a threaded pipe end connect and disconnect easily on that side, no clamp or welding required. Thread sealant tape (sold separately) prevents leaks in threaded connections. To prevent overtightening that could cause cracks and leaks, first finger-tighten fittings, then turn once or twice with a wrench.
