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.

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.

Tees have an offset branch so your line can drain. Also known as sanitary and eccentric tees, they’re often used where cleaning and inspections are frequent.

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.

270° bend connectors are also known as P-traps. Union connectors separate into three pieces for easy access to your line.

Adapters for glass pipe connect to older glass piping systems with a bead-to-bead clamp (not included).

Add a neutralization tank (sold separately) under your sink and fill it with limestone to safely discharge acidic waste.

Made of polypropylene, this gravity-flow pipe stands up to tough organic solvents, such as acetone, that would dissolve CPVC pipe. You can also use it for lines with highly corrosive acids, such as hydrochloric acid, and alkalies. This pipe meets strict ASTM specifications and testing requirements for material quality and product dimensions. It also meets ASTM and UL flammability standards. This pipe is known as schedule 40 pipe.

Connect clamp-on fittings to the grooved-ends of this pipe when you need frequent access to your line. If you need to trim down the pipe, you'll need a grooving tool (sold separately) to add a groove for your fitting. For a permanent connection, fuse socket-connect fittings on with an electrofusion tool (sold separately).

Made of CPVC, these fittings have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances. They meet NSF/ANSI 14 requirements for use in corrosive waste gravity-flow systems. Fittings are comparable to Corzan. They meet UL 94 V-0 for flame retardance and ASTM F2618 specifications and testing requirements for material quality. They are IAPMO certified to comply with the International Association for Plumbing and Mechanical Officials product performance standards and the Uniform Plumbing Code (UPC) for installation and repair of plumbing systems.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

270° bend fittings are also known as P-traps. They separate into three pieces, so you can access your line.

Offset tees are also known as sanitary tees and eccentric tees. They have an offset branch so the line can drain. Use them for applications that require frequent cleaning and inspecting.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings. These fittings meet NSF/ANSI 61 for use with drinking water, and they’re FDA compliant for direct contact with food. They also meet ASTM requirements for material and performance, and ISO requirements for dimensions.

Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size.
