PVC Internal and External Thread Repair Insert | G/PT/BSP Male-to-Female Reducing Bushing Pipe Fitting (1/2" to 2") - Atradesen

Thickened PVC Male-to-Female Thread Repair Inserts & Reducing Bushings

Convert and repair standard threaded ports inline with our thickened PVC male-to-female thread repair inserts, available at Atradesen.com. Crafted from potable water-grade PVC, these heavy-duty reducing bushings feature an integrated male-outer and female-inner thread design, allowing you to downsize piping connections directly without adding bulky multi-piece adapters.

With an enhanced structure engineered to withstand up to 16kg of pressure, these off-white threaded inserts are ideal for residential tap water networks, chemical pipelines, and agricultural irrigation manifolds.

Special Staggered Thickening Design

Standard reducing bushings often split under stress at the transition point where the outer male thread terminates and the inner female thread begins. Our PVC inserts solve this vulnerability with a specialized staggered thickening design. This added material increases overall structural density to support a 16kg (1.6 MPa) pressure rating, while the external hex-style ribs provide an excellent grip surface for pipe wrenches during high-torque tightening.

⚠️ Sizing & Thread Compatibility Guide

Plumbing nominal sizes do not represent direct caliper measurements. Please measure your pipe's outer diameter or thread diameter and verify with the guide below before placing your order:

• 1/2" (4分): Thread diameter measures approximately 20mm.
• 3/4" (6分): Thread diameter measures approximately 25mm.
• 1" (1寸): Thread diameter measures approximately 32mm.
• 1-1/4" (1.2寸): Thread diameter measures approximately 40mm.
• 1-1/2" (1.5寸): Thread diameter measures approximately 50mm.
• 2" (2寸): Thread diameter measures approximately 63mm.
• Note: These fittings utilize standard PT pipe threads, which are fully compatible with G-threads and British Standard Pipe (BSP) threadings.

Frequently Asked Questions (FAQ)

Q: Why is the wall thickness on these bushings uneven?

A: The uneven wall design is a deliberate engineering choice. By offsetting and thickening the material where the male and female threads overlap, we prevent stress fractures caused by water hammer shocks, making these much stronger than standard uniform reducing bushings.

Q: Can these PT threaded inserts be used with standard BSP female joints?

A: Yes. PT (Pipe Thread) standards conform to parallel pipe threads, making them fully interchangeable with BSP and G-threaded plumbing connectors. Always wrap standard PTFE tape clockwise around the male thread to secure a leak-free seal.
