ERA Mechanical Compression Fitting is a fitting that connect piping elements which require physical force to develop a seal or produce alignment. There are several materials of compression fittings, such as: Steel, Brass, Plastic. The most plastic material used is PP, there are also PE or PVC compression fittings.

PP compression fittings are widely used in water supply and irrigation. ERA  mechanical fittings are made by high quality PP material with UV protection, both material and fittings are approved use with drinking water. The threaded version is BSP. The high-quality material used in the product has an application in the area of water distribution, irrigation, swimming pools, and cable conduits.

Performance of PP：

PP is a crystalline polymer, commonly used plastic PP is the lightest, density is only 0.91g/cm3 (smaller than water). Among general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100℃, which can be boiled in boiling water. PP has good stress cracking resistance and high bending fatigue life, commonly known as"100 fold glue".

The comprehensive performance of PP is better than PE material. PP products light weight, good toughness, good chemical resistance. The disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce"copper damage", it has a shrinkage phenomenon, after stripping, easy aging, brittle, easy deformation. PP has been the main raw material for manufacturing fibers because of its coloring ability, abrasion resistance, chemical resistance, and favorable economic conditions.

PP is a kind of semi-crystalline material. It is harder than PE and has a higher melting point. Because homopolymer PP is very brittle when the temperature is above 0℃, many commercial PP materials are random copolymers with 1~4% ethylene or clip-on copolymers with higher ratio of ethylene content. Copolymer PP material has lower thermal distortion temperature (100℃), low transparency, low gloss, low rigidity, but has stronger impact strength. The strength of PP increases with increasing ethylene content

The Vica softening temperature of PP was 150℃. Due to its high crystallinity, the material has good surface stiffness and scratch resistance.

There is no environmental stress cracking problem in PP. PP is usually modified by adding glass fiber, metal additives or thermoplastic rubber. The MFR of PP turnover rate ranges from 1 to 40. Low MFR PP materials have better impact resistance but lower tensile strength. For materials with the same MFR, the strength of copolymer type is higher than that of homopolymer type.
