QSL-3/8-6 QSL-3/8-8 QSL-3/8-8-50 QSL-3/8-10 QSL-3/8-10-20 Festo QSL Series L-shape Push-in Fitting
Built to deliver reliable performance in demanding industrial environments, the Festo QSL Fitting features a durable construction with a body made of robust PBT plastic and critical components like the retaining claw made from high-alloy steel. This ensures a secure, vibration-resistant grip on the tubing without causing surface damage. The fitting maintains stable performance with a wide operating pressure of up to 14 bar and a temperature range from -10°C to +80°C, backed by NBR seals for leak-proof connections. This robust design guarantees long-term reliability and minimal maintenance for continuous operation in automated machinery and industrial automation systems.
