Clamp connectors let you connect CPVC grooved-end pipe fittings and pipe.
Clamp adapters let you connect CPVC grooved-end pipe fittings and pipe to metal grooved-end pipe fittings and pipe.
Clamp reducers allow you to connect CPVC grooved-end pipe fittings and pipe and transition from a larger pipe size to a smaller pipe size.

Easy-Access CPVC Pipe Fittings for Chemicals
- For Use With: Acetic Acid (10%), Calcium Chloride, Deionized Water, Hydrochloric Acid, Phosphoric Acid, Salt Water, Sodium Hydroxide, Sulfuric Acid (80%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D1784
- Pipe Nipples and Pipe: Use Schedule 80 CPVC Plastic
Also known as Victaulic fittings, these have grooved ends that connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Fittings are CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are comparable to Corzan. Fittings meet ASTM D1784 specifications and testing requirements for material quality.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

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

Fiberglass Pipe Fittings for Corrosive Chemicals
- For Use With: Acetic Acid (75%), Alcohol, Calcium Chloride, Chlorine, Fuel Oil, Gasoline, Hydrochloric Acid (37%), Nitric Acid (10%), Oil, Phosphoric Acid, Salt Water (30%), Sodium Hydroxide (50%), Solvents, Sulfuric Acid (70%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D3567
These fittings have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals. Fittings meet ASTM D3567 specifications for product dimensions.
To connect fittings to pipe, first sand the inside of the fitting and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8” thick. Repeat this process with the inside of the fitting, applying a layer approximately 1/16” thick. After sealant has been applied, push the fitting onto the pipe until it is fully engaged. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and fitting at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and fitting will be ready to use.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Right-Angle Flow Rectangular Manifolds
Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side.
PTFE manifolds have the best chemical and corrosion resistance of all the plastic and metal manifolds we offer, so they’re the best choice for acids and other highly corrosive substances. Do not use with deonized water at temperatures above 120° F.
Use a plug (sold separately) to close off any unused inlets and outlets.
