PPR Female-Threaded Straight Coupling | Double-Sided Female Thread Equal & Reducing Socket Joint (1/2", 3/4", 1") - Atradesen

Premium PPR Female-Threaded Straight Couplings (Equal & Reducing)

Seamlessly connect and extend your plumbing lines with our premium PPR double-sided female threaded straight couplings, available at Atradesen.com. Crafted from high-density, hot-melt grade PPR (Polypropylene Random Copolymer), these linear sockets are engineered for outstanding thermal stability, high pressure threshold, and long-term reliable service in both hot and cold potable water networks.

With G-thread connection sockets on both ends, these straight joints eliminate the need for complicated socket fusion welding at joining points, making them highly suitable for quick extensions, inline transitions, and equipment integration.

Equal and Reducing Connection Styles

We offer both standard inline extensions and diameter-transition options to fit your system design:

• Equal Couplings: Feature identical thread sizes on both ends (1/2" to 1/2", 3/4" to 3/4", 1" to 1" equal ports) for standard G-thread pipeline joining.
• Reducing Couplings: Designed to join two pipes of different sizes (e.g., transitioning 3/4" down to 1/2", or 1" down to 3/4") without requiring additional step-down adapters.

⚠️ Size Selection & Installation Guidelines

Review these dimensional details prior to ordering to prevent mismatching:

• Thread Standard Mapping: The thread specifications are based on G/BSP plumbing threads.
  • 1/2": Thread inner diameter measures approximately 20mm.
  • 3/4": Thread inner diameter measures approximately 25mm.
  • 1": Thread inner diameter measures approximately 32mm.
• Full Female Threading: Both ends of this straight connector feature inner threads. Ensure the male adapters or threaded pipes being connected match these specifications.
• Preventing Leaks: Plastic threaded joints must be sealed with PTFE thread seal tape (Teflon tape) wrapped around the male thread. Tighten components manually first, then apply a wrench to secure. Do not over-torque to prevent mechanical cracking of the plastic casing.

Technical Specifications

Frequently Asked Questions (FAQ)

Q: Can these PPR female couplings be connected to metal pipe threads?

A: Yes. These fittings are compatible with any standard G or BSP parallel male pipe threads of matching sizes (1/2", 3/4", or 1"). Wrapping threads with Teflon sealing tape is required for a secure seal.

Q: Is hot-melt welding required to install these female-threaded straight couplings?

A: No. Unlike slip-fit PPR fittings that require socket fusion machines, these threaded couplings are mechanical and install via standard screw connection directly onto male-threaded pipes.
