Product Description

Ashirvad Flowguard Plus CPVC Union provides a unique combination of permanent pipe connections with the ability to disconnect when needed. This three-piece fitting consists of two socket ends that are solvent-welded to pipes, plus a threaded collar nut that joins them together. The union allows for easy disassembly without cutting pipes, making it essential for equipment that requires periodic maintenance or replacement.

The precision-machined sealing surfaces ensure leak-free operation under full system pressure, while the robust threaded nut provides secure connection strength. Ideal for installations before water heaters, pumps, filters, and other equipment requiring future access. The CPVC construction maintains compatibility with the complete Flowguard Plus system while offering the serviceability of a threaded connection.

Recommended Applications

• Water Heater Connections: Before and after geysers for easy removal during maintenance or replacement
• Pump Installations: On suction and discharge sides of water pumps for servicing access
• Filter Systems: Before water filters, RO systems, and treatment equipment requiring periodic replacement
• Equipment Connections: Any appliance or device that may need future disconnection
• Meter Installations: Before and after water meters for easy removal and replacement
• Valve Access: Providing disconnection points for valve replacement without system drainage

Installation Guidelines

FAQs

1) What's the difference between a union and a coupler?

A coupler creates a permanent solvent-welded connection that cannot be disassembled without cutting. A union has a threaded collar nut that allows you to disconnect and reconnect the joint for maintenance. Use unions before equipment requiring future access and couplers for permanent pipe extensions.

2) How many times can I disconnect and reconnect a CPVC union?

CPVC unions can be disconnected and reconnected multiple times when done properly. The key is to avoid over-tightening which can damage the sealing surfaces. With proper handling, a union can be disassembled dozens of times throughout its service life without leaking.

3) Do I need PTFE tape on a CPVC union?

No, CPVC unions do not require PTFE tape. The seal is created by the precision-machined flat surfaces of the two union halves pressing together, not by threads. The threaded collar nut simply holds the halves together. Adding tape can actually prevent proper sealing.

4) Can I install a union in any orientation?

Yes, CPVC unions can be installed in any orientation - horizontal, vertical, or angled. However, for ease of future disassembly, install unions in accessible locations where you have room to use wrenches on the collar nut. Avoid installing unions in tight spaces or behind walls.

5) How tight should I make the union collar nut?

Hand-tighten first, then use a wrench for 1-2 additional turns until snug. The union should be tight enough to prevent leaks but not so tight that it damages the sealing surfaces. If leaks occur, check that sealing surfaces are clean and undamaged before over-tightening.
