3/4″ Plastic Washer and Brass Lock Nut

Description

A simple yet essential component for reliable water-pipe installations, the 3/4″ Plastic Washer and Brass Lock Nut provides a strong, leak-resistant connection when working with MDPE pipe systems.

Key Features & Advantages

• Secure thread seal — The brass lock nut threads onto standard 3/4″ BSP (or compatible) fittings, locking firmly in place to secure connections such as taps, valves or hose-tails. The included plastic washer helps create a tight, reliable seal that reduces leaks and ensures long-lasting performance.
• Corrosion-resistant brass — The nut’s brass construction offers excellent resistance to corrosion and dezincification in water systems, making it ideal for both fresh-water and irrigation setups.
• Adds stability to MDPE fittings — When used in conjunction with MDPE pipework, this washer plus lock-nut combo helps stabilise threaded joints, securing taps, bulkhead fittings or valves to tanks, water butts or manifolds. This prevents movement or loosening over time — especially useful in game-rearing, poultry or small-holding water systems.
• Simple to install & maintain — A no-frills but practical component: simply insert the plastic washer at the joint, screw on the brass nut, and tighten firmly. The design makes replacement or maintenance straightforward when servicing valves or taps.
