Product Description

Products Details

Malleable Iron pipe fittings 280 Hexagon Nipple. Nipple are male and male thread.Malleable iron Nipple are hexagon Nipple ,it is difference with steel Nipple. Malleable Nipple also named Hex Nipple. According to the weight ,we have heavy type Nipple ,medium type Nipple and light type Nipple. According to the Surface treatment ,we have hot-dip Galvanized Nipple ,electro Galvanized Nipple ,black Nipple. According to the thread Standard ,we have NPT thread Standard and BSP thread Standard ,and ISO 7-1,DIN Standard Nipple. Nipple connect two female thread pipe.The working press is PN16/PN25,363PSI,2.5MPA.Galvanized Nipple pipe fittings have high corrosion resistance and oxidation resistance. The Cast iron Nipple pipe fittings provided by Fluid Tech Group, after galvanized layer, have high thread accuracy, and the pipe fittings have good sealing after connection.

At both ends are threaded fittings is called nipple.

The shape is a three-dimensional stripe circular design, and the outer layer is engraved with three-dimensional stripes. On-site workers often call the nipple with threads at both ends as nipple, which is very inaccurate, and the real wire pairs should be internal joints (external threads) at both ends, and the size and sealing form of the threads at both ends are exactly the same. The pair wire is mainly used for matching hardware fittings, such as can be installed in various pipe interfaces. The filament is made of high-quality zinc alloy material and the color is silver.

1. Copper nipple: quick screw, direct head, right wire, straight through, direct wire (inner wire), inner and outer wire butt direct, pagoda, muffler, elbow, nozzle elbow, tee, plug, ferrule, all-in-one machine joint

2. Valves: cylinder joints (regulating valves), discharge valves, single pneumatic valves, check valves, needle valves, ball valves, anechoic throttle valves, air joints

3. Plastic pipes: PA pipe, nylon tube, PU pipe, trailer spiral pipe, PU spiral pipe, nylon pipe three-piece set: lining, ferrule, nut, 7-piece set

4. Iron nipple: carbon steel joint, direct head, elbow, carbon steel tee, Used in hardware, auto parts, pneumatics, plumbing, machinery, electronics and other industries
