Parker's WireFree Locking Clamp: Easy-fit Alternative to Wire Locking

Parker’s WireFree locking device for two and single ferrule compression fittings on instrumentation tubing provides a highly cost-effective alternative to wire locking.

It is five times stronger than a wire lock, can be fitted in minutes and is equally suitable for new and retrofit applications. The device is also ideal for replacing existing wire locks during standard MRO operations – the wire merely needs to be removed first.

Product Features:
  • Unique wire-free design – five times stronger than wire locks
  • Typically less than two minutes to install
  • 6Mo stainless steel construction with minimal crevices
  • Supplied preassembled – no separate parts
  • Straight, elbow, tee and cross configurations
  • Models for 1/4 - 1” inch (6 - 25 mm) fittings

Subsea. Strength is Everything

Parker’s unique WireFree locking device was originally developed for a leading supplier of instrumentation to the offshore oil and gas industry, which sought a better alternative to wire locking compression tube fittings on deepwater ‘Christmas tree’ fluid flow assemblies.

Designed as a ‘fit-and-forget’ solution, the patented device is fabricated almost entirely from 6Mo stainless steel for superb corrosion resistance, with
an open construction that minimizes crevices.

The WireFree locking device is supplied preassembled as a single part, simplifying installation significantly. Depending on configuration, it comprises one or more flexible clamp arms with pre-attached rigid support plates.

To lock both compression nuts on a standard 90˚ elbow fitting, for example, the installer simply places the clamp arms around the nuts and tightens a single securing screw to the recommended torque.

No modification, realignment or disassembly of the fitting is involved and the entire installation process typically takes less than two minutes.
