Thickened PVC Symmetrical Female Threaded Fitting | Double-Sided Coupling, 90-Degree Elbow, Three-Sided Tee (1/2" to 2") - Atradesen

Heavy-Duty Thickened PVC Female-Threaded Fittings (Couplings, Elbows & Tees)

Direct, branch, and secure your piping runs with our premium thickened PVC female-threaded fittings, available at Atradesen.com. Manufactured from non-toxic, lead-free, potable water-grade PVC, these heavy-duty connectors are offered in straight coupling, 90-degree elbow, and 3-way tee configurations to support versatile water-routing setups.

Featuring standard G/BSP/PT parallel internal threads on all ports, this industrial-grade connector series is highly compatible with standard household water pipes, pump connections, and filtration manifolds.

Specifically Reinforced Thickened Thread Ports

Standard plastic threaded joints are highly vulnerable to stress cracking, splitting, and stripping when overtightened or exposed to water hammer pressure surges. Our heavy-duty fittings are engineered with structural thickening around the body walls and extra reinforcement collars around every threaded port. This dramatically enhances overall structural integrity, ensuring they can support a high 1.6 MPa (16kg) pressure rating and be disassembled and reused repeatedly.

Three Symmetrical Configurations Available

• Double-Sided Female Coupling: Symmetrical straight-through connection for joining two male-threaded pipe runs.
• Double-Sided Female 90-Degree Elbow: Redirects water runs by 90-degrees around tight corners.
• Three-Sided Female Tee: Creates a balanced 3-way distribution junction for branching pipelines.

⚠️ Thread Sizing & Compatibility Guide

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

• 1/2" : Thread inner diameter measures approximately 20mm.
• 3/4" : Thread inner diameter measures approximately 25mm.
• 1" : Thread inner diameter measures approximately 32mm.
• 1-1/4" : Thread inner diameter measures approximately 40mm.
• 1-1/2" : Thread inner diameter measures approximately 50mm.
• 2" : Thread inner diameter measures approximately 63mm.
• Note: These are non-tapered parallel threads. Always wrap additional PTFE thread seal tape (Teflon tape) clockwise around the male threads to secure a watertight, leak-proof mechanical seal.

Frequently Asked Questions (FAQ)

Q: Why is a thickened PVC thread design highly important?

A: When tightening threaded fittings, the wedge action of standard male threads puts high outward radial stress on the female port. Symmetrical thickened walls distribute this stress evenly, preventing the plastic housing from cracking or stripping under wrench pressure.

Q: Are these PVC fittings safe for household drinking water lines?

A: Yes. Molded from lead-free, drinking water-grade PVC, these fittings are completely non-toxic and odorless. They are safe for potable water networks, delicate hydroponics loops, and marine aquascapes.
