Detailed description

Custom CNC Turned Multi-Ring Barbed Hollow Hose

Our Custom CNC Turned Multi-Ring Barbed Hollow Hose Fitting is a reliable fluid & pneumatic connecting component featuring multi-stage barb ridges and smooth hollow inner bore, designed for secure hose insertion and leak-proof tubing assembly. As a professional CNC turning manufacturer based in Dongguan, we produce customized barbed hose fittings with ±0.01mm ultra-precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for total length, outer diameter, inner bore size and barb quantity. These multi-ring barbed fittings are widely used for pneumatic hose connection, fluid tubing assembly, industrial pipeline fitting and equipment fluid transfer in automation, plumbing and industrial equipment industries.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi‑axis turning centers, metal bars are processed through continuous cutting, facing, grooving, threading and boring with computer‑controlled accuracy.
Compared with manual machining and conventional milling, precision CNC turning achieves stable dimensional tolerance down to ±0.01mm, smooth surface quality and outstanding consistency during mass production. It is widely applied to fabricate pins, shafts, bushings, connectors and threaded parts for mold, electronics, medical, automotive and automation machinery.
Equipped with secondary milling and cutting capacity, CNC turning supports complex customized profiles including stepped cylinders, grooved structures and multi‑sided profiles, satisfying diversified precision positioning component demands for industrial equipment.

Product Definition & Industrial Value

Multi-ring barbed hollow hose fitting is a tubing connecting fitting composed of multiple inverted barb ridges, smooth insertion end and hollow through bore. The multi-stage barb structure forms multi-point mechanical bite and layered sealing after inserting into flexible hose, effectively preventing hose from falling off under pressure and vibration; the smooth hollow bore ensures unobstructed fluid or gas flow with low resistance. It solves common industry pain points such as easy hose disconnection under pressure, poor sealing performance and complicated assembly with extra clamps. The integrally machined structure ensures stable connection strength and reliable sealing, effectively improving assembly efficiency and operation safety for fluid and pneumatic pipeline systems.

Our Product Service

We provide one-stop custom CNC turning service for multi-ring barbed hollow hose fittings for global pneumatic, fluid equipment and industrial pipeline suppliers. Our product scope covers various barbed hose connectors, hose tail adapters, tubing inserts and other non-standard precision turned pipe fittings. We complete full turning, multi-ridge barb forming, inner bore fine finishing, chamfering and deburring strictly based on customer engineering drawings. Value-added services include diversified surface treatment, full-dimension inspection, prototype sampling and large-batch OEM production.

5 Core Advantages

Multi-ring barb structure for reliable anti-loosening sealing

The precision-formed multi-stage barb ridges feature uniform height and sharp edge, which form firm multi-point mechanical interlock with the inner wall of the flexible hose after insertion, providing excellent pull-out resistance and layered sealing effect. It maintains stable connection without extra clamps under certain pressure and vibration, effectively reducing the risk of hose falling off and fluid leakage.

High-precision smooth hollow through bore

The inner bore is finely turned with high precision, featuring smooth wall and consistent diameter, which ensures unobstructed flow of fluid or gas with low resistance, and avoids turbulence and pressure loss. The strict coaxiality control between each barb section and the main body ensures smooth hose insertion and uniform stress on the hose wall.

Premium material with strong corrosion resistance

Standardly made of high-quality SUS304/SUS316 stainless steel, it has excellent corrosion resistance and fluid compatibility, suitable for water, gas, oil and most conventional fluid media. Optional materials such as brass and carbon steel are also available to match different application scenarios and cost requirements.

Integrally machined structure with high strength

The whole fitting is machined from solid bar stock in one clamping, with no welding or assembly joints, high structural strength and good pressure resistance. It can maintain stable shape and sealing performance under long-term pressure changes and frequent disassembly, with long service life.

Full-parameter drawing-based customization

All key parameters including total length, outer diameter, inner bore size, barb quantity and specification can be fully adjusted according to your 2D/3D drawings or physical samples. We accept both small-batch prototype verification orders for new product development and large-volume mass production orders for formal projects.

OEM Custom Service Range

We provide comprehensive customized solutions for custom multi-ring barbed hollow hose fittings and all kinds of precision CNC turned components. Available materials include SUS304/SUS316 stainless steel, carbon steel, C36000 brass and 6061‑T6 aluminum alloy, with sufficient bar stock to match different corrosion resistance, pressure resistance and cost requirements.
Our custom product range includes hose fittings, connecting shafts, bushings, threaded pipe fittings and other rotational precision machined parts. Selectable surface treatments: natural machined finish, passivation, polishing, zinc plating, nickel plating, black oxide and anodizing.
We can supply single parts or matched hardware kits according to assembly needs. Custom machining will be developed based on your drawings or samples. Small batch prototype testing is available before formal mass production.

Typical Application Scenarios

Our Custom CNC Turned Multi-Ring Barbed Hollow Hose Fitting is widely used in pneumatic system hose connection, fluid pipeline tubing assembly, industrial equipment fluid transfer, plumbing system hose fitting, hydraulic auxiliary pipeline connection and mechanical equipment gas-liquid tubing assembly.

A: We support a full range of common precision machining metals, including SUS304/SUS316 stainless steel, 1018/1045 carbon steel, 6061/7075 aluminum alloy, C36000 brass, copper and titanium. We can select suitable raw materials based on your product usage, working environment, strength requirements and budget.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

FAQ 4

Q: What surface finishing options do you provide for CNC turned metal parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
