Parker introduces new sleeved design for rectus series 26 couplers for pneumatic applications

24 June, 2025

The company says the Series 26 is a robust and universal standard quick connect coupling with a nominal diameter of 7.2 mm and is suitable for use in pneumatic applications of up to 35 bar. Available in brass or polymer, the couplers are now equipped with a newly engineered polymer sleeve, which ensures that the internal parts are protected against dirt penetration to enhance reliability and prolong service life.

Previously, the Series 26 couplers with a polymer sleeve were only available as a special product, but were highly regarded by leading manufacturers and Parker customers for their proven technology and high-quality materials.

Now available as standard, the new sleeved design features the same technical characteristics as existing models, ensuring the same level of performance and reliability. Features include a EURO profile, single-hand operation, connection, and disconnection strength, up to 35 bar working pressure, working temperature of -20°C to 100°C, and flow rates of 1,070 l/min (air).

This new polymer sleeve design brings additional advantages, including being lightweight and easier to handle, while offering better corrosion resistance for increased durability.

From an environmental perspective, the Rectus Series 26 couplers are produced using sustainable materials and manufacturing processes: reducing ecological impact, energy consumption, and carbon footprint to meet the growing demand for greener products.

Furthermore, the couplers are available in a variety of colors and textures that enhance aesthetics and visual identity. Their design makes them more comfortable to use thanks to a better grip and sensitivity to touch, thus meeting the needs of applications that involve frequent human intervention.

“Parker is committed to providing its customers with state-of-the-art, high-quality products and services, and the new design of the Rectus Series 26 couplers for air applications in standard environments is a testament to that commitment,” says Rodolphe Karpe, Business Unit Marketing Manager at Parker’s Low Pressure Connectors Europe (LPCE) Division.

The new, cost-efficient Series 26 couplers offer customers a streamlined range that reduces inventory and makes it easier to choose the right product for their pneumatic application. Moreover, the simplified offer means continued and market-proven, reliable products with short delivery times and a continuous high service level. This development is part of Parker LPCE Division’s dedication to meet trends in pneumatic applications, offering cost-efficient alternatives to pure metal couplers.
