UPVC Female Threaded Adapter

UPVC Female Threaded Adapter is a plug attached to a wire, cable, or piece of hardware and has one or more recessed holes with electrical terminals inside. It is designed so that a male connector with exposed conductors can be inserted snugly into it to ensure a solid physical and electrical connection.

A jack, outlet, or receptacle is another name for a UPVC Female Threaded Adapter (FAPT). The electrical conductors are not directly exposed when this type of connector is detached or removed. Therefore they are less prone to make unintended contact with exterior items or conductors.

A two- or three-prong electrical outlet, often known as a wall outlet, is the most common female connectors and fasteners. Telephone jacks, headset jacks, coaxial cable chassis connections, and some D-shell connectors for computer serial and parallel ports are common types.

Types of UPVC Female Threaded Adapter

1. Straight Female Threaded Adapter (Socket × Female Thread)

Most common type

  • One end: solvent-weld socket
  • Other end: female threaded
  • Used to connect uPVC pipe to male-threaded valves, taps, nipples

2. Female Threaded Adapter – BSP / NPT

Reducer Female Threaded Adapter

Different pipe and thread sizes

  • Socket size ≠ threaded size
  • Example: 32 mm socket × ¾″ female thread

3.Heavy-Duty / Industrial Female Threaded Adapter

Higher pressure design

  • Thicker wall
  • Usually PN16 or Schedule 80

Better resistance to cracking

4. Long-Neck Female Threaded Adapter

Extended threaded length

  • Longer female thread engagement
  • Reduced stress concentration

5. Female Threaded Adapter with Brass Insert

Plastic + metal hybrid

  • uPVC body with embedded brass female thread
  • Eliminates thread wear and cracking

6. Union-Type Female Threaded Adapter

Detachable connection

  • Includes union nut and seal
