Pneumatic Fittings: Technical DATA

Description: Designed for quick and tool-free installation onto nylon or polyurethane tubing. A stainless-steel grab ring bites into the tube for a secure, leak-proof connection that is easy to disconnect by pressing the collet.

Technical Specifications:

• Thread Types: M5, Rc(PT) 1/8, 1/4, 3/8, 1/2
• Tube Outer Diameters: Φ4, Φ6, Φ8, Φ10, Φ12 mm
• Seal: NBR O-ring
• Grab Ring: Stainless Steel
• Body: Brass, Nickel Plated
• Operating Pressure: 0 to 1.0 MPa
• Leakage: None at specified pressure range.

Common Types:

• Straight Connector: For inline connections.
• Elbow (90° & 45°): For directional changes in tight spaces.
• Tee Connector: For branching a single line into two.
• Bulkhead Union: For passing through panels or walls.
• Reducer: For connecting two different tube sizes.

 2. Compression & Barb Fittings

Description:

• Compression Fittings: Use a ferrule and nut to create a strong, permanent mechanical seal on plastic or metal tubing. Ideal for higher vibration environments.
• Barb Fittings: Feature a barbed stem that tubing is pushed over and secured with a clamp. Provides a strong, permanent connection for soft tubing (e.g., PVC, rubber).

Technical Specifications:

• Thread Types: Rc(PT) 1/8, 1/4, 3/8, 1/2
• Tube OD (Compression): Φ6, Φ8, Φ10, Φ12 mm
• Tube ID (Barb): Various sizes, typically matched to hose inner diameter.
• Body: Brass
• Ferrule (Compression): Brass or PPS Resin
• Operating Pressure: 0 to 1.0 MPa

Common Types:

• Straight, Elbow, Tee variants for both Compression and Barb styles.
• Male & Female Connectors.

Description: These fittings incorporate a one-touch shut-off valve. When disconnected, the valve automatically seals the port to prevent air loss from the main line, improving energy efficiency during maintenance.

Technical Specifications:

• Thread Types: Rc(PT) 1/8, 1/4, 3/8
• Tube Outer Diameters: Φ4, Φ6, Φ8, Φ10, Φ12 mm
• Valve Mechanism: Spring-loaded poppet valve with NBR seal.
• Body: Brass, Nickel Plated
• Operating Pressure: 0 to 1.0 MPa
• Flow Characteristics: Specified by Cv value (e.g., ~0.5 to 2.0 depending on size).

Common Types:

• Shut-off Straight Connector
• Shut-off Elbow
• Shut-off Tee

 4. Fittings with Rotating Section

Description: Feature a swivel mechanism that allows the connected tubing to rotate 360 degrees, preventing hose kinking and reducing stress, which extends tubing life.

Technical Specifications:

• Rotation: 360° continuous swivel.
• Thread Types: M5, Rc(PT) 1/8, 1/4
• Tube Outer Diameters: Φ4, Φ6, Φ8, Φ10 mm
• Swivel Seal: Precision NBR seal for low rotational torque and minimal leakage.
• Body: Brass
• Operating Pressure: 0 to 1.0 MPa

Common Types:

• Swivel Elbow
• Swivel Straight Connector

 5.Twist-Proof Piping

Description: A specialized fitting that allows the tubing to be bent in any direction without twisting the connection point at the port. Essential for applications with moving parts like robots, where hose management is critical.

Technical Specifications:

• Bending Angle: Up to 40° from center in all directions.
• Thread Types: Rc(PT) 1/8, 1/4
• Tube Outer Diameters: Φ6, Φ8, Φ10, Φ12 mm
• Mechanism: Special spherical structure with seal.
• Body: Brass
• Operating Pressure: 0 to 1.0 MPa

Common Types:

• Twistless Straight Joint
• Twistless 

Description: Modular manifolds that consolidate multiple air supply lines into a single, compact block. They simplify piping, reduce installation space, and provide a clean, organized air distribution point.

Technical Specifications:

• Material: Aluminum Alloy (main manifold), Brass/NBR (outlet fittings).
• Inlet Ports: Rc(PT) 1/4, 3/8, 1/2
• Outlet Ports: Multiple outlets (e.g., 2 to 10+), typically for Φ4, Φ6, or Φ8 mm tubing via push-in or threaded ports.
• Pressure Rating: 0 to 1.0 MPa
• Options: Available with integrated pressure regulators, flow control valves, and shut-off valves on each outlet.

Common Types:

• Basic Manifold Block: Multiple outlets from a single inlet.
• Modular Manifold Systems: Can be banked together to create larger distribution units.

 7. Separate Type Fittings

Description: Refers to a two-piece fitting system where the port connector (e.g., a male thread) and the tube socket are separate. This allows for easy pre-assembly and disassembly in hard-to-reach places.

Technical Specifications:

• Thread Types: M5, Rc(PT) 1/8, 1/4
• Tube Outer Diameters: Φ4, Φ6, Φ8, Φ10 mm
• Connection: The socket piece screws onto the port piece, capturing the tube.
• Seal: NBR O-ring on the port piece.
• Body: Brass
• Operating Pressure: 0 to 1.0 MPa

Common Types:

• Separate Straight Connector
• Separate Elbow Connector

 8. Release-Ring Cover Fittings

Description: A safety-enhanced version of the push-in fitting. A protective cover surrounds the collet, requiring the user to pull the ring back to release the tube. This prevents accidental disconnection.

Technical Specifications:

• Thread Types: Rc(PT) 1/8, 1/4, 3/8
• Tube Outer Diameters: Φ6, Φ8, Φ10, Φ12 mm
• Release Mechanism: Pull-back ring cover.
• Body & Cover: Brass / Engineering Plastic (for cover)
• Operating Pressure: 0 to 1.0 MPa

Common Types:

• Release-Ring Straight
• Release-Ring Elbow
