Manufacturing Process Insight
Production utilizes our advanced Swiss-style CNC Lathes (Sliding Headstock).
One-Setup Machining
Turning, facing, threading, and knurling are completed in a single operation to guarantee varying concentricity within 0.01mm.
Precision Knurling
Unlike standard rolling, we use a cut-knurling process to create sharp, well-defined diamond patterns that provide superior grip without flaking.
Thread Protection
Automated thread checking during production ensures every part meets the Go/No-Go gauge standards before leaving the machine.
Key Features & Benefits
Material Excellence
Machined from Brass C36000, offering excellent corrosion resistance and natural antimicrobial properties.
Tactile Grip
The deep diamond knurling allows for tool-free assembly and disassembly, ideal for maintenance-heavy environments.
Leak-Proof Design
High-precision threads (M20 standard or custom pitch) ensure a tight seal against gas or liquid leakage.
Surface Finish
Parts are degreased and passivated, resulting in a bright, oxidation-resistant gold finish.

Frequently Asked Questions
-
Q What materials can be used besides Brass C36000 for this type of connector?We can machine similar connectors from a range of materials including stainless steel (303/304/316), aluminum alloys (6061/7075), and other copper alloys depending on your application's pressure, temperature, and corrosion requirements.
-
Q What surface treatment options are available for brass connectors?Standard options include as-machined (Ra 0.8), nickel plating, chrome plating, electroless nickel, and passivation. Each treatment is selected based on the end-use environment, such as high-humidity or chemical-exposure conditions.
-
Q Can you produce connectors from customer-supplied drawings or samples?Yes. We accept 2D drawings (PDF, DWG), 3D CAD files (STEP, IGES, SolidWorks), or physical samples for reverse engineering. Our engineering team will provide a DFM (Design for Manufacturability) review before production begins.
-
Q What quality inspection and documentation do you provide with each order?Every shipment includes a full inspection report with dimensional measurements, surface roughness data, thread gauge records (Go/No-Go), and material mill certificates. CMM reports and PPAP documentation are available upon request for automotive or medical-grade applications.
-
Q What is the typical lead time for a new OEM brass connector project?For prototypes (1–10 pcs), lead time is typically 5–7 business days after drawing confirmation. For production runs of 1,000–10,000 pcs, standard lead time is 15–25 business days depending on complexity and surface treatment requirements.
-
Q Are these brass connectors suitable for use in high-pressure pneumatic or hydraulic systems?Yes. The M20 x 1.5 precision thread combined with the tight ±0.01mm tolerance and Ra 0.8 surface finish ensures excellent sealing performance. For specific pressure ratings, we recommend providing your operating conditions so we can confirm material and thread specification suitability.
