Stainless steel tube fittings are precision-engineered components designed for leak-proof containment in industrial instrumentation, hydraulic, and pneumatic systems. Standard specifications cover sizes from 1/16' to 2' (2 mm to 50 mm), operating pressures up to 10, 000+ PSI, and compliance with ASTM A276 and ASME SA276 material standards. Material Grades & Standards • Grades: SS 304, SS 304L, SS 316, SS 316L, and Alloy variants. SS 316 provides superior marine and chemical corrosion resistance. • Specifications: ASTM A276, ASTM A479, ASME SA276, ASME SA479 (for bar stock); ASTM A182 (for forged fittings). • Wall Thickness: 0.6 mm to 6.0 mm depending on outer diameter and pressure rating. Dimensions & Pressure Ratings • Size Range: Imperial (1/16” to 2” OD) and Metric (2 mm to 50 mm OD). • Working Pressure: Vacuum up to 6, 000 – 10, 000 PSI (varies by wall thickness and OD size). • Temperature Limits: -425°F to 1200°F (-254°C to 649°C) depending on the seal and grade. Thread & Connection Types • NPT (National Pipe Thread): ASME B1.20.1 • BSPT / BSPP (British Standard Pipe): ISO 7 / ISO 228 • Configuration: Single or double-ferrule compression, socket weld, and threaded options. Common Fitting Configurations • Unions & Connectors: Straight line joining • Elbows: 45° and 90° directional changes • Tees & Crosses: Branching flow into multi-directional splits • Reducers: Adapting between varying tube dimensions • Caps & Plugs: Sealing open tube ends If you need specific details, please let me know:What tube outer diameter (OD) or size do you need?What is your required pressure or temperature rating?Are you looking for single or double ferrule compression fittings?
