At Perfect Engineers, we are a leading manufacturer and exporter of SS 304 Instrumentation Tube Fittings, built to deliver precision, leak-free sealing, and pressure integrity under demanding industrial conditions. Offered under our trusted PE-LOCK brand, these ferrule-type compression fittings are engineered to connect stainless steel tubes in instrumentation, process control, and fluid distribution systems.
Manufactured from high-grade Stainless Steel 304 (AISI 304), these fittings provide corrosion resistance, cost-efficiency, and global compatibility, making them a go-to solution for industries like oil & gas, chemical, pharma, HVAC, marine, and power generation.
SS 304 Instrumentation Fittings are mechanical tube connectors made from austenitic stainless steel (AISI 304) and are used to join, branch, or adapt tubing lines in instrumentation and fluid systems. These fittings rely on a ferrule-based compression seal—either single or double ferrule—to ensure a gas-tight and vibration-resistant connection without welding or threading.
They are ideal for moderate pressure and temperature environments where both corrosion resistance and economical performance are key.
