The CPVC Solvent Cement Male Threaded Coupler is an adapter in chlorinated polyvinyl chloride (CPVC) with one solvent-cement socket and one G / ISO 228-1 parallel male thread with hex flats. The CPVC Solvent Cement Male Threaded Coupler joins CPVC pipe to female-threaded equipment in potable water and industrial corrosive lines, combining a permanent glued joint with a wrench-tightened thread. Rated to 90°C, this CPVC solvent cement male threaded coupler resists most acids, alkalis and oxidizing media at pumps, meters and tank connections.

Key Features of CPVC Solvent Cement Male Threaded Coupler
- One solvent-cement CPVC socket, one reinforced male parallel thread (G / ISO 228-1).
- CPVC end bonds with solvent cement into a permanent glued joint; threaded end detaches.
- Integral hex flats allow wrench tightening to female-threaded valves and equipment.
- Long-term service up to 90°C; resists acids, alkalis, salts and oxidizing media.
- Connects CPVC pipe to female-threaded pumps, meters, tanks and fittings.
Manufacturing Process of CPVC Solvent Cement Male Threaded Coupler
Each CPVC Solvent Cement Male Threaded Coupler is injection molded from CPVC with a precision male thread and hex flats, then the solvent socket is reamed and 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 Male 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 Male 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 Male Threaded Coupler
- Male-thread connections in potable hot and cold water CPVC pipework.
- Pump, meter and valve adapters in water treatment and RO systems.
- Male-thread take-offs on chemical transfer and acid/alkali lines.
- Glued male adapters to tank fittings in ultrapure water and pharma skids.
- Corrosive transitions to metal equipment in plating and desalination plants.
Application Scenarios of CPVC Solvent Cement Male Threaded Coupler
The CPVC Solvent Cement Male Threaded Coupler is the glued-to-male-thread transition with wrench flats used to connect CPVC pipe to female-threaded equipment in water and corrosive industrial systems.
