Product Description

Ashirvad Flowguard Plus CPVC Coupler is an essential fitting for creating straight, leak-free connections between two CPVC pipes of equal diameter. Manufactured from high-grade CPVC compound with FlowGuard Gold technology, this coupler provides exceptional strength and durability in hot and cold water distribution systems. The precision-molded socket design ensures proper pipe insertion depth and optimal solvent cement bonding for permanent, pressure-tight joints.

The coupler's smooth interior bore maintains consistent water flow without turbulence or pressure drop, while the corrosion-resistant CPVC material eliminates the rust and scale buildup common with metal couplings. Ideal for extending pipe runs, repairing damaged sections, or connecting pre-cut pipe lengths, this fitting is compatible with all Ashirvad Flowguard Plus CPVC pipes and fittings when installed with recommended solvent cement.

Recommended Applications

• Pipe Extension: Joining two pipe sections to extend hot or cold water distribution runs
• Repair Work: Replacing damaged pipe sections by cutting out the defective portion and coupling new pipe
• Straight Connections: Creating continuous pipe runs in bathroom, kitchen, and utility room plumbing
• Geyser Installations: Connecting hot water outlet pipes from geysers to distribution lines
• Overhead Tank Lines: Joining cold water supply pipes from overhead tanks to fixtures
• Manifold Systems: Creating distribution manifolds for multi-outlet plumbing systems

Installation Guidelines

FAQs

1) What is the difference between a coupler and a union in CPVC fittings?

A CPVC coupler creates a permanent solvent-welded connection that cannot be disassembled without cutting the pipe. A CPVC union provides a detachable connection with a threaded nut that allows for easy disassembly and reassembly for maintenance. Use couplers for permanent installations and unions where future disconnection may be needed, such as before water heaters or pumps.

2) Can I use a CPVC coupler to join pipes of different diameters?

No, a standard CPVC coupler is designed to join two pipes of the same diameter only. To connect pipes of different sizes, you need a CPVC Reducer Coupler (also called reducing coupler), which has different socket sizes on each end. For example, a 3/4" x 1/2" reducer coupler connects a 3/4" pipe to a 1/2" pipe.

3) How long should I wait before pressurizing a CPVC coupler joint?

After solvent cementing a CPVC coupler, allow 15 minutes set time before handling, 1 hour before moving or supporting the joint, and 24 hours before full pressure testing and commissioning. Rushing the curing process can result in weak joints and potential leaks. Temperature and humidity affect curing time—in cold or humid conditions, extend curing time by 50%.

4) Can CPVC couplers be used for underground water lines?

Yes, CPVC couplers can be used for underground water distribution when properly installed. Ensure pipes and fittings are protected from UV exposure before burial and laid in a sand bed to prevent damage. CPVC is corrosion-resistant and unaffected by soil chemicals, making it suitable for buried applications. However, avoid prolonged sun exposure during storage and installation.

5) What sizes are available in Ashirvad Flowguard Plus CPVC Couplers?

Ashirvad Flowguard Plus CPVC Couplers are available in standard sizes including 15mm (1/2"), 20mm (3/4"), 25mm (1"), 32mm (1-1/4"), 40mm (1-1/2"), and 50mm (2"). The most commonly used sizes for residential plumbing are 15mm and 20mm for fixture connections and 25mm for main distribution lines. Always match the coupler size to your pipe diameter for proper fit.
