CPVC Pipe Fittings for Hot Water

Made of CPVC, these fittings can handle high temperatures. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. They also have good corrosion resistance. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.
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 regulatory limits on VOCs (Volatile Organic Compounds).

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. 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.
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall, tank, or panel to create an inlet or outlet for faucets, pipes, and spigots.

Gravity-Flow Polypropylene Pipe Fittings for Corrosive Chemical Waste
- For Use With: Deionized Water, Hydrochloric Acid, Oil, Phosphoric Acid, Salt Water, Solvents
- Maximum Temperature: 220° F
- Specifications Met: ASTM D4101, ASTM D635, ASTM F1412, UL 94 V-2
- Compatible with Gravity-Flow Polypropylene Pipe for Corrosive Chemical Waste
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.

Gravity-Flow Polypropylene Pipe for Corrosive Chemical 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).

High-Purity Polypropylene Pipe Fittings for Corrosive Chemicals
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.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping. The connectors are 316 stainless steel for excellent corrosion resistance. They stand up to wet environments, just like 304 stainless steel, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.
To install, chamfer and deburr both ends of the pipe you need to join. Mark each pipe adjacent to the connector bands and apply 10 layers of the PTFE tape directly over each line. Doing this creates a seal between the sleeve and the pipe for extra leak protection. Then, center the FEP sleeve over the tape and use a heat gun to shrink the sleeve onto the pipe. Next, center the connector and tighten the clamps to 60 inch-lbs. to form a tight seal. Finally, test for leaks.
