CPVC Pipes & Fittings

SuperMax Masterflow™ CPVC pipes and fittings

SuperMax Masterflow™ CPVC pipes and fittings are premium-quality products manufactured using high-grade raw material, i.e., Chlorinated Polyvinyl Chloride is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin, which is significantly more flexible and can withstand higher temperatures than standard PVC.

SuperMax Masterflow™ CPVC pipes are lightweight, non-corrosive, long-lasting and they are manufactured using lead-free compounds. Hence,  safe, healthy, and environmentally friendly.

We recommend use of our CPVC pipes for water supply and distribution in both domestic and industrial applications for water service temperature up to 93° C.

CPVC pipes SDR 11 & SDR 13.5 are available in sizes from 15 mm (1/2”) to 50 mm (2”) and meet the requirement of IS: 15778. CPVC fittings are available in sizes from 15 mm (1/2”) to 50 mm (2”) and meet the requirement of ASTM D 2846 in Copper Tube Sizing (CTS). CPVC fittings from 65 mm (2.1/2”) to 150 mm (6”) in Schedule 40 and Schedule 80 are manufactured as per ASTM F 438 & ASTM F 439 in Iron Tube Sizing (ITS) respectively.

We ensuring stringent quality checks across all stages of manufacturing against product specifications such as IS and ASTM standards gives products a high degree of reliability, making them a preferred choice of leading engineers, builders, contractors, plumbers and valued customers.

CPVC Brass Fittings:

SuperMax uses high-quality CPVC brass fittings, which are durable and anti-corrosion. Generally, brass inserts are used for reinforcing male and female threads on CPVC fittings, and they creates a secure joint between objects without damaging them and also require proper engagement with other materials such as CP taps or any other connection to be tightened.


SuperMax CPVC Ball valves:

SuperMax CPVC ball valves are top-quality valves that are absolutely ideal for a wide range of applications and It is made in accordance with ASTM D2846. The materials were selected for their ability to withstand high temperatures and the fact that they're designed for both hot and cold water systems. These valves available in sizes ranging from 20 mm to 75 mm.


  1. Ideal for Hot & Cold water plumbing systems Suitable up to 93°
  2.  No Bacterial Growth
  3. Freedom from toxicity, Odours and Tastes.
  4. Safe for drinking water
  5. Low thermal Expansion
  6. Cost effective
  7. 50 Years life span
  8. Easy to handle and Installation

Installation Procedure of the CPVC Plumbing System

  1. Cut the Pipe to the required dimension
  2. Remove Burrs and Filings
  3. Prepare the Piping for Fitting
  4. Apply Solvent Cement
  5. Immediately after cement application, insert the pipe into the fitting socket and rotate 1/8 to 1/2 turn until the fitting-stop is reached. The fitting should be properly aligned for installation at this time, and the pipe must meet the bottom of the fitting socket. Then, hold the assembly in place for 10 to 30 seconds to ensure initial bonding and to avoid push-out.
  6. A bead of cement should be evident around the pipe and fitting juncture. If this bead is not continuous around the socket shoulder, it may indicate that insufficient cement was applied. In this case, the fitting should be discarded and the joint reassembled. Cement in excess of the bead may be wiped off with a rag.

System Leak Test: A leak test is strongly recommended after the installation of a CPVC plumbing system to ensure there is no leakage. No additional pressure is required only water gravity is enough to perform the test. The method is to connect the plumbing system to the water storage tank, either temporarily or permanent installation and other opening ends to be connected with taps or blinded off, open the valve from main header and check all the joints for the leakage before plastering.

Duration of the test: The test should be performed at least 20 minutes for a small system, and a big system could be tested in 30 minutes or as required or portion by portion after successful results, depending on its size.

If there is leakage, immediately cut the portion and repair and re-test as per the installation procedure. If there is no leakage have found, then the system is completely sound, and should be proceed for next step i.e. water flushing. Special care should be taken for the pipes that go under the floor and the tile or marble installation comes after the test, then there should be chances of leakage of the water because the tile or marble fitter is not aware of your CPVC pipe installation underneath it. Therefore, they should be made aware of it or supervise to ensure there is no damage. SuperMax offers an extended warranty if this test has taken place, kindly refer to the below section about product warranty.

System Water Flushing: Water flushing is necessary after the above leak test is performed, as it cleans the complete system with water and all residues and waste will come out through the system. The taps that are used for testing and flushing are required to be inspected for all the dust and debris and reinstalled. The test should be done in at least 20 minutes for a small system, and a big system could be tested in 30 minutes or portion by portion after successful results, depending on its size. No additional pressure is required only water gravity is enough; just fill the tank and open the ends to check for debris, dust, and waste. Note that taps connected to the test can be used temporarily and, after use, can be replaced with permanent taps in the system.

Why CPVC Pipes and Fittings are failed sometimes?

As CPVC pipes age, they become more brittle and can shatter or crack with a slight impact. This can lead to severe problems and significant repair work. According to the study, the failure of CPVC pipes and fittings could be caused by the following factors:

  1. Due to substandard materials used.
  2. Due to improper installation by unskilled manpower.
  3. Due to insert of brass CPVC fittings dismantling.
  4. Due to quality and substandard materials used together.
  5. Due to local Solvents used for joining the pipe and fittings?
  6. Due to Hot outdoor temperatures accelerate the deterioration and breakdown of these pipes.
  7. Due to Worsen effect of Chlorinated water on the CPVC pipes.

How to overcome from all above factors?

  1. Always use standard and branded materials, like SuperMax CPVC Pipe and Fittings, which are manufactured against product specifications such as IS and ASTM standards.
  2. Well-trained and certified manpower is required for the installation of CPVC plumbing systems.
  3. Use standard materials like SuperMax CPVC fittings to avoid the dismantling of brass inserts from fittings.
  4. Always use quality and standard materials only, without mixing other materials.
  5. Always use SuperMax  Fast Fix™Solvent for joining the CPVC pipe and fittings for the system's extended warranty.
  6. In the hottest areas, the plumber shall conceal the CPVC pipe and fittings into the wall to avoid the deterioration and breakdown of the pipes.
  7. Always use SuperMax pipes and fittings to prevent effect of chlorinated water on the CPVC pipes.
  8. Ensure that proper pipe clamp support is provided.
