These fittings utilize a compression mechanism that creates a leak-tight seal by compressing a ferrule against the tube when the nut is tightened. Available in grades SS 304 and SS 316, these fittings offer excellent corrosion resistance and mechanical strength. The compression design eliminates the need for welding or threading, making installation quick and straightforward. These fittings are ideal for instrumentation lines, process piping, and general industrial applications where moderate pressures and temperatures are encountered. The precision-machined components ensure consistent performance and long service life even under demanding operating conditions.Stainless Steel 316 Compression Fittings – Superior Corrosion ResistanceStainless Steel 316 Compression Fittings represent the premium choice for applications requiring exceptional corrosion resistance and durability. The 316 grade contains molybdenum, which significantly enhances resistance to chloride corrosion, making these fittings ideal for marine environments, chemical processing, and pharmaceutical applications. These fittings demonstrate superior performance in acidic and alkaline environments, maintaining structural integrity under extreme conditions. The austenitic microstructure provides excellent mechanical properties, including high tensile strength and impact resistance. Our SS 316 compression fittings are manufactured to strict tolerances ensuring optimal sealing performance and are available in both L-grade (low carbon) and standard configurations to meet specific application requirements.Stainless Steel Single Ferrule Compression Fittings – Simplified DesignStainless Steel Single Ferrule Compression Fittings feature a streamlined design utilizing a single ferrule component to create an effective seal. This configuration is particularly suitable for applications where ease of assembly and disassembly is crucial. The single ferrule design reduces the number of components, minimizing potential leak paths and simplifying maintenance procedures. These fittings are engineered with precision-machined sealing surfaces that ensure reliable performance across a wide range of pressures and temperatures. The single ferrule system provides consistent bite into the tube wall, creating a permanent connection that maintains integrity throughout numerous pressure cycles. Ideal for instrumentation applications, analytical systems, and process lines requiring frequent disconnection for maintenance or calibration.Stainless Steel Double Ferrule Compression Fittings – Enhanced Sealing PerformanceStainless Steel Double Ferrule Compression Fittings incorporate an advanced two-ferrule design that provides superior sealing performance and tube gripping capability. The front ferrule creates the primary seal while the back ferrule provides tube support and additional gripping action. This dual-ferrule system distributes stress more evenly along the tube, reducing the risk of tube deformation or cracking. The progressive tightening action ensures optimal seal formation without over-stressing the tube material. These fittings are engineered for high-pressure applications and environments where vibration resistance is critical. The double ferrule configuration allows for partial disassembly and reassembly while maintaining seal integrity, making them ideal for systems requiring periodic maintenance access.Material Grades & International StandardsStandard/RegionGrade DesignationEquivalent MaterialsKey PropertiesASTM (USA)ASTM A276 Grade 304/316UNS S30400, UNS S31600High strength, corrosion resistantDIN (Europe)DIN 1.4301, DIN 1.4401X5CrNi18-10, X5CrNiMo17-12-2European automotive standardsJIS (Japan)JIS SUS304, SUS316SUS304L, SUS316LLow carbon variants availableBS (British)BS 304S15, BS 316S31304S11, 316S11British standard specificationsIS (India)IS 1570 Grade 304, 316304, 316, 316L, 316TiIndian standard specificationsGB (China)GB 0Cr18Ni9, 0Cr17Ni12Mo2304, 316, 321, 310SChinese national standardsMaterial Properties & Performance CharacteristicsPropertySS 304SS 316SS 316LTest StandardTensile Strength (MPa)515-620515-620485-620ASTM A370Yield Strength (MPa)205 min205 min170 minASTM A370Elongation (%)40 min40 min40 minASTM A370Hardness (HRB)92 max95 max95 maxASTM E18Operating Temperature-196°C to 400°C-196°C to 400°C-196°C to 400°CASTM A240Pressure RatingUp to 6000 PSIUp to 6000 PSIUp to 6000 PSIASME B31.3Manufacturing Processes & Advanced MachineryOur state-of-the-art manufacturing facility employs advanced precision machining technologies to produce high-quality Stainless Steel Compression Fittings.
