PVC External Thread Plug | BSP Male Threaded Pipe End Cap Screw Plug with O-Ring Seal (1/2" to 2") - Atradesen

Premium PVC Male External Threaded End Plugs (BSP Standard)

Seal and terminate your pipeline runs securely with our premium PVC male external threaded end plugs, available at Atradesen.com. Crafted from high-density, impact-resistant PVC, these male thread cap plugs offer a corrosion-proof, rust-free solution for closing off unused G/BSP standard female threaded sockets in home water supply networks, irrigation systems, and chemical lines.

Designed for rapid and tool-free installation, these white pipe plugs are highly resistant to UV radiation and chemical degradation, making them suitable for both indoor residential use and harsh outdoor environments.

Dual Design Head Configurations

To provide optimal torque and leak-proof performance based on specific pipe diameters, this product series features two standard head configurations:

• Hexagonal Head with O-Ring Gasket (Small Sizes: 1/2", 3/4", 1"): Features a standard hex head design and comes pre-equipped with a high-grade black rubber O-ring gasket. This ensures a reliable, drip-tight seal upon contact with the female thread shoulder, without necessarily requiring Teflon tape.
• Square Raised Drive Head (Large Sizes: 1-1/4", 1-1/2", 2"): Features a solid, heavy-duty raised square head. The robust profile is built to withstand high manual torque when tightened or disassembled with standard pipe wrenches or crescent wrenches.

⚠️ BSP Thread Diameter & Caliper Guide

Plumbing nominal sizes do not represent direct physical measurements. Please measure your pipe internal diameter or female thread opening before purchasing to ensure a proper fit:

• 1/2" BSP Male: Thread outer diameter (caliper reading) measures approximately 20mm.
• 3/4" BSP Male: Thread outer diameter (caliper reading) measures approximately 25mm.
• 1" BSP Male: Thread outer diameter (caliper reading) measures approximately 32mm.
• 1-1/4" BSP Male: Thread outer diameter (caliper reading) measures approximately 40mm.
• 1-1/2" BSP Male: Thread outer diameter (caliper reading) measures approximately 46mm.
• 2" BSP Male: Thread outer diameter (caliper reading) measures approximately 58mm.

Technical Specifications

Frequently Asked Questions (FAQ)

Q: Why do larger BSP sizes (like 1-1/4" to 2") feature a square head instead of a hex head?

A: Larger diameter pipes require higher tightening torque to establish a secure seal. The square head provides a much larger contact surface for standard plumbing wrenches or crescent wrenches, preventing the tool from slipping or rounding off the corners under heavy torque.

Q: Do I need to wrap Teflon thread seal tape on the plugs with O-Rings?

A: Generally, no. For smaller sizes (1/2" to 1") equipped with our black rubber O-ring gaskets, the rubber seal compresses against the female thread shoulder to prevent leaks. However, if the female thread has minor imperfections or is slightly deformed, wrapping a few turns of Teflon tape around the plug threads can provide additional sealing security.
