One-touch pneumatic fittings come in a diverse range of types, each engineered to meet specific industrial needs, environmental conditions,
and installation requirements. Below are the key categories of these versatile pneumatic fittings:
Common Pneumatic Push-In Fittings
As the most widely used type of one-touch pneumatic fitting, common pneumatic push-in fittings are characterized by their high availability
and broad applicability. They are stocked in a variety of metric sizes and PT thread specifications, making them readily accessible for quick deployment.
Constructed with a PBT body, brass threaded components, a POM (polyoxymethylene) push button, 316 stainless steel reeds, and NBR sealing rings,
these pneumatic fittings balance durability and cost-effectiveness. They are available in standard colors like black, blue, and white, with special options
(yellow, green, red) for easy system identification. Ideal for low-pressure pneumatic piping systems, they ensure reliable connections in everyday industrial setups.
Mini-Type Pneumatic Push-In Fittings
Mini-type pneumatic push-in fittings share a similar structural design to their common counterparts but stand out for their compact, space-saving dimensions.
This small size makes them indispensable in tight or confined installation environments where larger pneumatic fittings cannot fit.
They excel in applications such as automated robotic arms, integrated pneumatic piping systems, and precision machinery—settings where space is at a premium.
Despite their diminutive size, these mini pneumatic fittings maintain the same quick-connect functionality and secure locking performance as standard models.
Full Stainless Steel Push-to-Connect Fittings
For harsh environments, full stainless steel push-to-connect fittings are the go-to choice. Every component of these pneumatic fittings—including the body,
threads, push button, and locking reed—is crafted from high-grade stainless steel (typically 304, 316, or 316L), with FKM (fluorocarbon or Viton) sealing rings for enhanced chemical resistance.
These robust pneumatic fittings thrive in chemically corrosive settings (e.g., strong acids, alkalis) and extreme conditions involving high temperatures or pressure.
They can withstand operating temperatures up to 200°C and working pressures as high as 30Bar (3.0MPa), making them a reliable choice for demanding industrial processes.
Full Brass Nickel-Plated One-Touch Pneumatic Fittings
Full brass nickel-plated one-touch pneumatic fittings combine strength and corrosion resistance, featuring a fully nickel-plated brass body and push button, 
stainless steel reed lock rings, and NBR sealing rings.
This category of pneumatic fittings is divided into two main styles based on structure:
• Reed-style: Mimicking the design of common push-in pneumatic fittings, this style uses a reed mechanism for easy insertion and removal of pneumatic tubing,
ensuring quick installation and maintenance.
• Integrated-style: Unlike the reed design, this style eliminates the internal reed and replaces it with an integrated locking device and push button.
This robust structure allows it to handle significantly higher working pressures—up to 50~70Bar—making it suitable for high-pressure pneumatic systems.
•
High-Quality SMC-Standard One-Touch Pneumatic Fittings
Engineered to meet the stringent standards of SMC pneumatic fittings, these high-quality one-touch pneumatic fittings offer superior performance compared to common models.
They boast a sleek appearance, precision craftsmanship, enhanced sealing capabilities, and a longer service life, making them a premium choice for applications where reliability and durability are critical.
In addition to the above, specialized options such as food-grade pneumatic fittings (designed for hygiene-critical industries like food and beverage) and custom-made pneumatic fittings (
tailored to unique project requirements) are also available to address niche needs.
No matter the application—whether in standard low-pressure systems, tight spaces, harsh environments, or high-pressure setups—there is a one-touch pneumatic fitting designed to deliver secure,
efficient, and long-lasting performance.
