Our GLL 304 stainless steel pneumatic connecting tube (male and female connection) is a high-performance pipe component designed for industrial pneumatic systems. It is made of high-quality 304 stainless steel and combined with CNC precision processing technology to achieve fast and reliable connection between male and female heads. The product has the characteristics of corrosion resistance, high pressure resistance, low leakage rate, etc., and is widely used in automation equipment, food packaging, medical equipment, automobile manufacturing and other fields.
GLL 304 stainless steel pneumatic connecting tube (male and female connection) Core advantages:
1. 304 ss material advantages: corrosion-resistant and durable
Anti-Corrosive Properties: GLL uses high-quality 304 stainless steel, containing 18% chromium and 8% nickel, offering excellent resistance to water, steam, weak acids, and alkalis.
Excellent temperature resistance: GLL pneumatic connecting tube (male and female connection) can perform stably in a wide temperature range of -20℃ to 300℃, suitable for extreme working conditions.
Mechanical strength: High hardness, wear resistance.
2. CNC precision machining: high precision, zero leakage
Precise size: processed by CNC machine tools, the tolerance is controlled within ±0.01mm, ensuring perfect matching of male and female heads.
Smooth surface: The surface roughness after processing is as low as Ra0.4μm, which reduces the flow resistance of the medium and reduces the risk of leakage.
Structural optimization: integrated molding design, no welding gap, to avoid leakage problems caused by welding defects.
3. Male and female connection design: quick docking, error-proof installation
Quick connection: the male head automatically locks after being inserted into the female head, no complicated tools are required, saving installation time.
Error-proof design: keyway positioning structure prevents reverse insertion and avoids damage caused by misoperation.
Multi-specification compatibility: supports metric, imperial and various standard pipe diameters.
4. Sealing performance: double protection, safe and worry-free
Sealing is done with FKM or NBR O-rings, which are suitable for air, water, and oil.
Cone sealing: The connection end adopts a cone design, which fits tightly with the pipeline to further prevent leakage.
FAQ
Q1: How does CNC machining affect the precision of male and female connections?
Tolerance Control: CNC machining enables tight tolerance control, maintaining the male outer diameter and female inner diameter within ±0.01 mm. This high precision ensures a seamless and secure fit between components. Dimensional Uniformity : During mass production, GLL’s CNC machining guarantees uniform dimensions across parts, significantly reducing the risk of leakage or misalignment often associated with manual assembly.
Q2: Is the working pressure range adjustable?
Yes, GLL provides standard (0~1.6MPa) and high-pressure (up to 3.0MPa) customization services, and specific working condition parameters must be provided.
Q3: Does the connecting pipe support multiple media?
The default is to adapt to compressed air.Transmitting water, oil, or other media, replace the O-ring with one made of a suitable material—such as FKM for oil resistance or EPDM for water resistance.
Q4: What should I pay attention to during installation?
Make sure the end faces of the male and female heads are clean to avoid dust or burrs scratching the O-ring.
It needs to be aligned vertically during insertion to avoid oblique insertion causing the seal to shift.
It is recommended to perform a pressure test before the first use and put it into operation after confirming that there is no leakage.
