Versatile Compression Fittings 16x1/2 16x3/4 20x3/4 for Plumbing Needs

Product Material & Size​

• Premium Construction: Crafted from high-grade brass (body) and stainless steel (gasket/collar), these fittings resist corrosion, high pressure (up to 16 bar), and temperatures from -20°C to 120°C. The brass ensures durability, while the stainless steel components enhance sealing and longevity.​

• Precise Sizing: 16×1/2" (for small fixtures), 16×3/4", and 20×3/4" (for main lines). Each fits standard pipes, with compression nuts and collars that create a tight seal without threading pipes, simplifying installation.​

Use Scenarios​

• Residential Plumbing: Perfect for connecting water lines to sinks, toilets, or washing machines. 16×1/2" fittings handle small flows, while 20×3/4" sizes serve main water lines, ensuring secure connections in kitchens and bathrooms.​

• Commercial Spaces: Hotels and offices use them to repair or extend plumbing networks, supporting multiple fixtures with consistent water flow. Their versatile sizes adapt to various pipe diameters.​

• Light Industry: Suitable for refrigeration, heating, or fluid transfer systems, where leak-proof compression seals prevent fluid loss and maintain operational efficiency.​

How to Use​

1. Preparation: Cut pipes to match fitting sizes (16mm/20mm), deburr ends, and ensure they’re clean. Slide the compression nut and collar onto the pipe in that order.​

2. Installation: Insert the pipe into the fitting body until it hits the internal stop. Tighten the nut by hand to seat the collar, then use a wrench to tighten 1–2 more turns for a secure seal—avoid over-tightening to prevent damage.​

3. Maintenance: Inspect periodically for leaks. If leaking, gently retighten the nut. Clean with a damp cloth; avoid harsh chemicals to preserve metal components.​
