Stainless steel pipe fittings are useful in many applications because of their high tolerance to corrosive substances like acids and oils. Many industries use piped products and require stainless steel fittings and nipples. Stainless steel nipples may feature a hexagonal section at their centers so they can be easily grasped with a wrench when tightening or loosening this joint. The advantage of using stainless steel fittings and nipples is that they provide excellent resistance to corrosion, thermal variation, ultraviolet ray action, mechanical shock, and fire. These stainless steel fittings and nipples are easy to clean.
