Compact Solutions for Tight Spaces
Mini Female Thread Fitting products are designed for small-scale hydraulic and pneumatic piping systems. Their compact structure makes them suitable for applications with limited installation space. Our products feature bore diameters from Φ1.2mm to Φ40mm, thread sizes from M2 to M48, and overall lengths from 5mm to 120mm. These fittings provide reliable fluid connections for miniature equipment, precision instruments, and compact automation systems.
Precise Bore Dimensions for Leak-Free Sealing
Bore accuracy and sealing surface quality directly affect fitting performance. We control bore tolerances within ±0.005mm and achieve surface roughness of Ra0.4μm for internal bore surfaces. For larger specifications, we guarantee sealing surface roughness up to Ra1.6μm. Smooth bore surfaces reduce fluid resistance and minimize particle buildup inside the fitting. Precise dimensions ensure stable tube installation and reduce leakage risks during long-term operation.
Specialized Swiss-Type Machining
Our Mini Female Thread Fitting manufacturing process is supported by high-precision Swiss-type machines. Tsugami S206A and Citizen A20N Swiss-type automatic lathes are used for producing small-diameter components with high length-to-diameter ratios. These machines complete turning, drilling, and tapping processes in a single setup, improving production efficiency and consistency. Our factory applies strict material segregation procedures to prevent mixing between different specifications. Each production process is recorded to ensure complete batch traceability. We have accumulated extensive experience in manufacturing miniature precision parts for semiconductor equipment and medical devices.
Comprehensive Quality Assurance System
Our quality assurance system covers every production stage. Incoming quality control includes raw material inspection and rejection of non-conforming materials. In-process quality control includes first-article inspection, regular dimensional checks, and immediate corrective actions when abnormalities occur. Final inspection covers dimensions, appearance, and functional performance before shipment. Every Mini Female Thread Fitting order includes complete inspection records for customer verification. If any quality issue occurs after delivery, our engineering team provides quick support and prepares one-page quality reports or 8D corrective action reports when required.
