Stainless steel body with AISI 316 L composition provides outstanding corrosion resistance and hygiene capabilities, making it suitable for aggressive environments and where cleanliness is critical. This translates to lower maintenance costs and extended service life in food and beverage processing, chemical handling, and similar industries. The push-in design enables rapid tube insertion and removal, reducing assembly time on the shop floor and in the field while minimizing tool requirements. Positive tube anchorage ensures a secure, leak-resistant connection even under vibration or dynamic loads, which lowers downtime and rework. The compact straight geometry is ideal for crowded panel spaces and hard-to-reach installations, delivering reliable performance without footprint penalties. The hex socket feature on straight adaptors allows tool-assisted installation, improving torque control and repeatable sealing essential for quality assurance. A wide operating range of -15 to 225 °C and 0 to 20 bar makes this adaptor versatile across climates and processes, from cold sanitization cycles to hot air applications. The compatibility with standard Pneufit S tubing PA2-0004100 and PA2-0004025C reinforces supply chain predictability and simplifies stocking for OEMs and maintenance teams.

FAQs
The S01250428 is a straight 4 mm port, R1/4 thread adaptor designed for 4 mm O/D tubing. It is part of the Pneufit S family and pairs with standard PN tubing PA2-0004100 and PA2-0004025C. Its stainless steel body ensures reliability in harsh environments, while its compact form supports dense panel layouts and easy field retrofits.
This adaptor supports an operating temperature range from -15 to 225 degrees Celsius and a pressure range of 0 to 20 bar (0 to 290 psi). These ranges make it suitable for both cold sanitization cycles and higher-temperature pneumatic operations commonly found in industrial automation and process control.
Yes, the adaptor is designed with corrosion resistance and cleanability in mind, aligning with the hygiene requirements of food and beverage environments. Its stainless steel AISI 316 L body minimizes corrosion risk and simplifies sanitization, helping to ensure safe, compliant pneumatic connections in processing lines.
The straight Pneufit S adaptors feature a hex socket to facilitate hex-key installation. This enables controlled tightening, reduces the risk of over-torquing, and ensures consistent sealing performance in maintenance and commissioning tasks, which is especially valuable in tight spaces or when performing field upgrades.
Stainless steel Pneufit S fittings offer superior corrosion resistance, higher temperature tolerance, and better chemical compatibility than many plastic options. They support longer service life in aggressive environments, lower total cost of ownership, and improved reliability for critical compressed air circuits in manufacturing and process industries.
