Compact Push-In Fittings – Imperial (NPT) / Metric (BSPT) – Legris Style
HAK Pneumatic Compact Push-In Fittings — also known as pneumatic push-to-connect fittings, one-touch fittings, or Legris-style fittings — are engineered for space-saving pneumatic installations that demand reliable and leak-free performance.
Each fitting features a stainless steel tube-gripping claw, internal collar, and quick-release sleeve (collet) for fast and secure connections. Disconnection is just as easy — requiring no tools. The threaded portion is made from corrosion-resistant nickel-plated brass, while the main body is molded from durable nylon, making these fittings ideal for high-vibration and demanding environments.
This compact design is perfect for high-density or space-restricted systems, and all models are fully interchangeable with Legris-style fittings, ensuring compatibility and flexibility.
