The CPVC Solvent Cement Female Threaded Coupler is an adapter in chlorinated polyvinyl chloride (CPVC) with one solvent-cement socket and one G / ISO 228-1 parallel female thread. The CPVC Solvent Cement Female Threaded Coupler joins CPVC pipe to male-threaded equipment in potable water and industrial corrosive lines, giving a permanent glued joint on one side and a serviceable thread on the other. Rated to 90°C, this CPVC solvent cement female threaded coupler resists most acids, alkalis and oxidizing media around pumps, valves and meters.

Key Features of CPVC Solvent Cement Female Threaded Coupler
- One solvent-cement CPVC socket, one reinforced female parallel thread (G / ISO 228-1).
- CPVC end bonds with solvent cement into a permanent glued joint; threaded end is detachable.
- Connects CPVC pipe directly to male-threaded pumps, valves, filters and meters.
- Long-term service up to 90°C; resists acids, alkalis, salts and oxidizing media.
- Molded thread insert avoids stress cracking; hex-free compact one-piece body.
Manufacturing Process of CPVC Solvent Cement Female Threaded Coupler
Each CPVC Solvent Cement Female Threaded Coupler is injection molded from CPVC around a precision female-thread interface, then the solvent socket is reamed and both ends are gauge-checked before cementing. Solvent cement is applied to the cleaned socket and pipe spigot, which are then held until the glued joint cures into a single continuous CPVC structure.
Critical Process Parameters of CPVC Solvent Cement Female Threaded Coupler
- CPVC compound is processed inside its narrow melt-temperature window to avoid degradation.
- Socket inner diameter and spigot interference are controlled to the CPVC solvent-cement fit tolerance.
- Cement coating is even and full-length; set and cure times follow the cement manufacturer schedule before pressure testing.
- Wall-thickness uniformity and roundness are checked to safeguard pressure rating.
- 100% visual and dimensional inspection, with batch pressure and hydrostatic testing.
Raw Material Characteristics of CPVC Solvent Cement Female Threaded Coupler
- Body in CPVC (chlorinated polyvinyl chloride), joined with CPVC solvent cement.
- Long-term service temperature up to 90°C, well above conventional UPVC.
- Excellent resistance to acids, alkalis, salts and many oxidizing media.
- Flame retardant and self-extinguishing with a high limiting oxygen index (LOI).
- Smooth non-scaling inner surface keeps flow efficient and biofilm low.
Typical Applications of CPVC Solvent Cement Female Threaded Coupler
- Equipment connections in potable hot and cold water CPVC systems.
- Pump, valve and filter connections in water treatment and RO plants.
- Female-thread take-offs on chemical and acid/alkali dosing lines.
- Glued female adapters for instruments in ultrapure water skids.
- Corrosive equipment connections in plating and desalination plants.
Application Scenarios of CPVC Solvent Cement Female Threaded Coupler
The CPVC Solvent Cement Female Threaded Coupler is the glued-to-thread transition used wherever CPVC pipe meets a male-threaded pump, valve or fitting in water and corrosive industrial systems.
