CPVC Pipe Fitting

Chlorinated Polyvinyl Chloride (CPVC) pipes and fittings are thermoplastic materials manufactured using CPVC resins. These are among the most durable and high-performance piping materials used globally for over 60 years. CPVC is more flexible and can withstand higher temperatures compared to standard PVC pipes.

CPVC is highly resistant to chemicals, heat, and pressure, making it an ideal choice for residential, commercial, and industrial plumbing systems, including fire sprinkler applications.

Ajay CPVC plumbing fittings are manufactured using a premium blend of CPVC material, ensuring superior performance in both hot and cold water distribution systems. With advanced technology and high-quality raw materials, Ajay Pipes delivers reliable CPVC piping solutions.

CPVC Pipe Fitting Types and Varieties

1. CPVC Plain Pipe Fittings

CPVC plain fittings are used to connect two or more CPVC pipes using solvent cement. These fittings are available in various types:

• Tee and Reducing Tee
• Elbow and Reducing Elbow
• 45 Degree Elbow
• Socket / Coupler and Reducing Coupler
• Bushings
• Step Over Bend
• Long Bend
• End Cap
• 3-Way Elbow

These fittings are widely used in permanent plumbing systems.

2. CPVC Threaded Pipe Fittings

Threaded fittings are used to connect pipes with bathroom fixtures and plumbing equipment such as taps, showers, pumps, and tanks. Threads can be CPVC or Brass.

Common types include:

• Male Threaded Adaptor (MTA)
• Female Threaded Adaptor (FTA)
• Brass Tee
• Brass MTA / FTA
• Brass Elbow

Brass insert fittings are recommended for hot water applications due to higher strength and durability.

3. CPVC Union

A CPVC union is a combination of threaded and plain adaptors along with a threaded ring. It allows easy connection and disconnection of pipes without cutting them, unlike socket joints which are permanent.

4. CPVC Valves

CPVC valves are used to control the flow of water in a piping system. Common types include:

• CPVC Ball Valve
• CPVC Concealed Valve

These are essential for flow regulation in plumbing systems.

5. CPVC Flange

Flanges are used to connect pipes, valves, pumps, and other equipment. They allow easy maintenance and inspection.

A flange joint is created by bolting two flanges together with a gasket in between for proper sealing.

6. CPVC Tank Nipple

Tank nipples are used to connect the plumbing system with overhead tanks. They are available in both single-thread and double-thread configurations.

Sizes of CPVC Pipe Fittings

CPVC fittings are available in the following sizes:

Copper Tube Size (CTS)

• ½” (15 mm)
• ¾” (20 mm)
• 1” (25 mm)
• 1¼” (32 mm)
• 1½” (40 mm)
• 2” (50 mm)

Iron Pipe Size (IPS)

• 2½” (75 mm)
• 3” (90 mm)
• 4” (110 mm)
• 6” (160 mm)
• 8” (200 mm)

CPVC Pipe Fitting Standards

CPVC fittings are manufactured as per international standards:

• ASTM D2846 (Copper Tube Size)
• ASTM F438 and ASTM F439 (Iron Pipe Size – Schedule 40 & 80)
• Indian Standard IS 17546 (introduced in 2021)

These standards ensure quality, safety, and performance.

CPVC Plumbing Fittings Joining Techniques

1. Solvent Cement Joint

Plain CPVC fittings are joined using solvent cement, creating a strong and permanent bond between pipes.

2. Threaded Joint

Threaded joints connect CPVC pipes with other plumbing components like valves, pumps, and tanks. Teflon tape is used as a sealing material to prevent leakage.
