Waltech tube connectors

Our Waltech tube connector series offers reliable, leak-free design with high bending and impulse resistance. With three different ways to create a connection, it provides a complete solution for any tube-fitting needs and can meet a wide range of application challenges.

The design features enable simple, safe, and repeatable manual assembly, while our high-performance machines make assembly quicker and easier. In addition, our unique Guardian Seal surface plating enables high corrosion resistance without affecting assembly strength.

Which system is right for you?

The core product in our Waltech series is the Walpro cutting ring system, which enables metal tube connector systems to be set up manually. However, our capabilities go well beyond simple metallic sealing cutting ring systems. To ensure we deliver the best performance and leak-free operations, we’ve enhanced the core system to support specific needs:

  • Choose Walpro cutting ring system if you need a cost-efficient, easy solution that also allows manual assembly. It enables leak-free performance and short bending lengths for greater application flexibility.
  • Choose Walring cutting ring system if you have a manual assembly process and want to reduce errors. It enables additional soft sealing and easy assembly.
  • Choose Walform tube connectors for the most demanding, high-pressure, high-vibration applications where safety is crucial. It enables additional sealing, easy machine assembly, and robust performance.

WALFORM tube connectors additional options

  • Walform-SR: Extends Walform’s advantages to thin-wall tubing, with an additional support ring behind the formed that tube which increases vibration and bending stress resistance.
  • Walform-M: Enables metallic sealing without a soft seal, for applications with aggressive media or very high temperatures.

Exceptional vibration and bending resistance

  • Walpro: Offers better holding as the shoulder sits on and touches the clamps at full length.
  • Walring: Improves clamping for superior resistance to vibration and bending stress.
  • Walform: Cold forming and soft edges counteract even the toughest vibration and bending.

Outstanding assembly features

  • Simple, fast, and safe assembly
  • Lower tightening torque
  • Unmistakable pressure point to prevent over- or under-assembly
  • Unlimited reassembly with no performance impact
