◆ Variety of Materials and Sizes: SMC offers a wide range of materials (such as stainless steel, brass, and conductive resin) and sizes, allowing you to select the perfect fitting for your application.
To ensure you select the appropriate SMC Standard Pneumatic One Touch Fitting for your needs, here are the general technical parameters to consider:
◆ Applicable medium: Compressed Air
◆ Body materials: Brass, Zinc alloy and POM
◆ Seal materials: NBR
◆ Working pressure: 0-1.0MPa.
◆ Working temperature: -5-70℃
A one touch fitting is a type of pneumatic connector that enables fast and secure attachment of air hoses to components without the need for additional tools.
These fittings work by using a push-in mechanism, which allows users to quickly connect and disconnect tubes with minimal effort.
The pressure rating of SMC fittings typically ranges from 0.05 MPa (approximately 0.5 bar or 7.25 psi) to 1 MPa (approximately 10 bar or 145 psi), depending on the specific fitting series and its application.
Different SMC fitting series may have slightly different pressure ratings, so it’s essential to check the specifications for each series to determine the exact pressure range they can handle.
◆ The KQ2 series is designed for a pressure range up to 1 MPa (145 psi).
◆ The KQG2 series also offers a similar pressure range but is specialized for steam applications and can handle high temperatures.
◆ Other series, like KR or KA, may have pressure ratings suitable for lower pressures or specific applications like vacuum or high-temperature environments.
SMC offers a wide variety of one touch fittings, each designed to meet specific requirements for different industrial applications.
Here are some of the most commonly used SMC One Touch Fittings:
The KQ2 series is one of the most versatile SMC Standard Pneumatic One Touch Fittings. Available in both metric and inch sizes, this series comes in a variety of sizes, body styles, and thread types.
The KQ2 features a special profile seal that allows it to handle a wide range of pressures, from a low vacuum to a pressure of up to 1 MPa.
The release collar on the KQ2 fitting enables easy removal of the tubing with a low disconnection force, ensuring that maintenance and changes are simple and quick.
Made from SUS316 stainless steel, the KQG2 series is designed for use with steam and is grease-free.
This series is compatible with a variety of tubing materials, including FEP, PFA, nylon, soft nylon, polyurethane, and polyolefin.
The KQG2 is compact and lightweight, and it offers more configuration variations and tube sizes than the previous KQG series, making it ideal for environments that demand high durability and flexibility.
The KR series is a flame-resistant one-touch fitting that is effective in a range of pressures, from a low vacuum up to 145 PSI.
It is designed with a special profile to ensure positive sealing and minimal resistance when inserting tubes.
These fittings are particularly useful in confined spaces, as both the body and threaded portion can rotate, offering added flexibility for installation in tight areas.
The KA series is an antistatic one-touch fitting, suitable for use in copper-free applications and vacuum environments (with a max pressure of -100 kPa).
Constructed from conductive resin, the KA fittings and tubing ensure static dissipation, making them ideal for sensitive systems.
Additionally, they meet flame-resistant standards (UL94 V-0), ensuring they can withstand harsh environments.
The KP series is designed for clean room blow-off systems and drive air systems.
These fittings are oil-free, and their liquid-contact areas are non-metallic, which ensures contamination-free operation.
All parts are cleaned, assembled, and double-packaged in a cleanroom environment.
The KPQ/KPG fittings are constructed from polypropylene resin, ensuring they meet the stringent requirements of cleanroom operations.
TheKE series is a pressure relief valve fitting that can release residual pressure from a cylinder to the atmosphere.
These fittings are available in two types: the one-touch fitting type and the Rc(PT) screw type.
The KE series ensures that pneumatic systems maintain the correct pressure balance, enhancing the longevity and performance of pneumatic actuators.
The KC series features self-sealing fittings, which are particularly useful in areas where pressure cannot be shut off.
These fittings have a built-in self-seal mechanism that prevents air from escaping when the tube is removed, making them ideal for systems that require constant pressure.
The KC series includes 10 styles, including models that are electroless nickel-plated for copper-free applications.
The KQB2 series is a compact and lightweight fitting that uses electroless nickel-plated brass components.
It has a maximum operating temperature of 150°C and is suitable for use with fluids and environments experiencing significant temperature changes.
The KQB2 offers 17 configuration models and is compatible with tube sizes from Ø3.2 to Ø16 and 1/8" to 1/2".
Available with various connection threads like M, R, Rc, UNF, NPT, or G, the KQB2 offers a broad range of customization options for your system.
SMC one touch fittings are used in a wide range of industries and applications, including:
◆ Automation Systems: Ideal for quick and secure connections in automated machines and robotic systems.
◆ Manufacturing Plants: Used in production lines and assembly systems, providing ease of installation and maintenance.
◆ Cleanroom Applications: The KP series is especially popular in cleanroom blow-off systems and drive air systems.
◆ Packaging and Food Production: Used to ensure contamination-free air supply in packaging and food processing machines.
◆ Medical Devices: Used in pneumatic medical equipment, where precision and reliability are crucial.
SMC Standard Pneumatic One Touch Fittings provide an efficient and reliable solution for various pneumatic systems.
With their broad range of types, materials, and configurations, these fittings can meet the needs of virtually any industrial or commercial application.
Whether you require stainless steel fittings for steam applications, flame-resistant options for hazardous environments, or oil-free fittings for cleanrooms, SMC has a fitting to match your requirements.
