Precision Machined Brass C36000 Pneumatic Push-In Fitting with 0-1.6 MPa Working Pressure CNC Turning Parts

Pneumatic push in fitting CNC turning parts are machined from C36000 brass bar for the exacting sealing and release performance required in compressed air systems. Each fitting body features precisely turned barb seats, O-ring grooves and thread forms that must hold pressure without leakage at working pressures up to 1.6 MPa. We produce bodies, collars and release sleeves with controlled surface finishes so that push-in connectors operate smoothly and seal reliably over hundreds of insertion cycles.

• Pressure Tested Seals: Optional 100% air test at 1.6 MPa guarantees leak-free performance
• Precision Thread Forms: R, G, NPT and metric threads gauged 100% for reliable connections
• Smooth Barb Surfaces: Ra 0.8 barb finishes prevent tube damage and premature leakage
• Nickel Plated Option: Bright nickel plating resists corrosion in humid shop environments
• Consistent Release: Tight control of sleeve bores ensures smooth push-in and release action
• High Volume Capability: Multi-spindle production keeps unit cost low for volume fitting lines

Used in pneumatic control cabinets, air preparation units, robotic gripper systems, packaging machinery and workshop air networks for reliable push-in tube connections with quick assembly.

15+ Years of CNC Turning Experience - Our workshop has been dedicated to precision CNC turning since 2009. Over 1,200 custom turning projects delivered across automotive, medical, electronics and hydraulic industries give our engineers the practical experience to solve complex machining challenges before they reach your production line. Every project starts with a DFM (Design for Manufacturability) review, where our team refines your drawings to reduce cost and improve repeatability without compromising function.

Engineering Expertise - Our process engineers average 12 years of hands-on CNC programming experience with Fanuc and Siemens controlled lathes, including multi-axis and Swiss-type machines. We maintain an ISO 9001:2015 certified quality system and our QC team is trained in GD&T interpretation, CMM programming and SPC process control. Prototype samples are typically delivered within 5-7 working days, backed by full dimensional reports.

Authoritative Manufacturing Partner - We export to 40+ countries and serve 500+ active B2B customers, including tier-1 automotive suppliers and medical device manufacturers. Our facility holds ISO 9001:2015 certification, and material suppliers are audited annually with full traceability certificates (MTC) kept on file for every batch. CE and RoHS compliance documents are available upon request.

Reliability You Can Verify - Every batch is 100% inspected before shipment: critical dimensions are checked with CMM (Coordinate Measuring Machine), optical comparators and calibrated micrometers, and inspection reports are provided with each delivery. Our on-time delivery rate stands at 98.5% over the last 24 months, and we offer a 12-month workmanship warranty on all machined parts.

Q1: What is the minimum order quantity (MOQ)?
Our standard MOQ is 100 pcs for stock materials, but we accept trial orders from 10 pcs for prototype validation. The MOQ can be discussed based on part size, material and process complexity.

Q2: How long does delivery take?
Prototype samples are ready in 5-7 working days. Mass production normally takes 12-18 working days after sample approval, depending on quantity and surface treatment lead time. Urgent orders can be scheduled on our 24-hour shift line.

Q3: How do you control quality for large batches?
We follow a closed-loop QC system: first-article inspection, in-process SPC sampling, and 100% final inspection of critical dimensions. Full inspection reports and material certificates are shipped with every order, and traceability records are kept for 5 years.

Q4: Can you work from samples or just drawings?
Both. We accept 2D/3D drawings (STEP, IGES, PDF, DWG) and physical samples for reverse engineering. Our engineers will provide a free DFM suggestion and quotation within 24 hours of receiving your files.

Parts are individually protected with anti-rust oil (where applicable), separated by partition trays or bubble wrap, and packed in export-grade corrugated cartons or wooden cases for heavy batches. We ship via DHL, FedEx, UPS, TNT and sea freight (FOB/CIF/DDP terms available).
