Material: Typically made of 304 or 316L stainless steel, offering strong oxidation resistance and acid-alkali corrosion resistance.
Structure: Features different sizes at both ends (connecting large and small-diameter pipes for seamless transition) and an M-profile press design. A specialized anti-aging, food-grade O-ring is fitted in the protruding U-shaped groove at the end.
Specifications: Nominal pressure ≤1.6MPa, applicable temperature range -20℃~110℃, compatible with stainless steel welded pipes of Φ15～Φ108.
Reliable & Safe Connection: High press connection strength resists vibration. One-time press-fitting eliminates loosening risks from house vibration, water hammer, pipe resonance, or earthquakes, ensuring firm connection and tight sealing.
Efficient Construction: No on-site welding or threading. Installation time is 1/3 that of welded/threaded fittings, shortening project timelines and cutting labor costs. The site stays clean with no fire hazards.
Corrosion Resistance & Long Lifespan: Stainless steel forms a chromium oxide protective film (regenerates quickly if damaged), ensuring corrosion resistance. Service life aligns with the building’s lifespan.
Hygienic & Eco-Friendly: Only stainless steel contacts water after press-fitting, preventing water contamination and meeting hygiene standards for drinking water systems.
Material Savings: No threading allows thin-walled pipes. Larger inner diameter of pipes (same nominal size) enables smaller pipe diameters for the same flow, saving materials.
Suitable for Recessed Installation: Meets recessed installation needs, reducing leakage risks in hidden environments, lowering maintenance costs, and avoiding major building damage (compact joints).
