Perfect Engineers is a leading manufacturer and global supplier of SS 316 Instrumentation Tube Fittings, engineered for leak-proof, corrosion-resistant, and high-pressure applications. Manufactured under the trusted PE-LOCK brand, these precision fittings offer interchangeability, long service life, and superior performance even in aggressive industrial environments.
Our SS 316 ferrule-type compression fittings are widely used in oil & gas, chemical processing, marine, offshore, pharmaceutical, power plants, and aerospace industries where reliability and resistance to chlorides, acids, and extreme temperatures are essential.
SS 316 Instrumentation Fittings are high-grade compression fittings made from AISI 316 stainless steel (UNS S31600), known for its superior corrosion resistance, mechanical strength, and chemical compatibility. These fittings are used to connect tubes to tubes or tubes to threaded ports via single or double ferrule compression sealing.
Ideal for harsh service conditions, SS 316 fittings outperform SS 304 in chloride-rich or acidic environments, offering extended system reliability.
