PVC Hex Nipples
Overview
PVC Hex Nipples are short, threaded pipe connectors used to join two female-threaded fittings or components in a piping system. Their characteristic hexagonal center allows for easy tightening with a wrench. Made from corrosion-resistant PVC (Polyvinyl Chloride), these hex nipples are lightweight, cost-effective, and suitable for a variety of plumbing, irrigation, and light industrial applications.
Key Uses & Applications
Plumbing & Residential Water Systems
Connecting valves, elbows, tees, or other fittings in home or light commercial plumbing. Quick fixes or modifications to existing PVC pipe runs without expensive metal components.
Irrigation & Landscaping
Joining sprinkler heads, drip lines, or water manifolds in gardens and landscaping projects. Lightweight nature simplifies handling and reduces strain on above-ground lines.
Pool & Spa Equipment
Coupling pumps, filters, and other pool components using threaded connections. Corrosion-resistant PVC ensures a long lifespan in chlorinated or saltwater conditions.
Aquatic & Hydroponic Systems
Providing safe, non-corrosive connections in aquariums, ponds, or hydroponic setups. Maintains a leak-free seal for efficient water circulation.
Light Industrial & Chemical Handling
Used in low-pressure, mild chemical environments where PVC compatibility is acceptable. Easy to replace or modify piping without specialized tools.
Product Highlights
Corrosion-Resistant Construction
PVC is immune to rust and scale buildup, extending service life under normal wet conditions. Suitable for freshwater, saltwater, and many dilute chemicals.
Hexagonal Body
Provides a convenient gripping surface for wrenches, ensuring secure tightening and easy disassembly. Minimizes the risk of damage to threads when applying torque.
Lightweight Design
Far less heavy than metal counterparts, simplifying transportation and installation. Reduces stress on piping systems in overhead or suspended lines.
Various Thread Standards
Commonly available in NPT (National Pipe Taper), BSPT, or other regional threading formats. Confirms compatibility with local plumbing codes or industrial standards.
Multiple Sizes
Ranging typically from 1/2" to 4" (or larger, depending on manufacturer). Covers a wide array of flow and capacity needs.
