PE-LOCK Nut & Ferrule – Critical Compression Components for Tube Fittings

At Perfect Engineers, we manufacture and supply precision-engineered Nut and Ferrule Sets under our brand PE-LOCK — the heart of any leak-proof single ferrule tube fitting system. Our high-performance nuts and ferrules ensure consistent sealing, proper grip, and dimensional integrity across high-pressure gas and fluid systems.

Built to match international instrumentation standards, PE-LOCK Nut & Ferrule sets are trusted in process control, chemical, hydraulic, power, and aerospace applications worldwide. They are designed to be interchangeable, reliable, and reusable without compromising sealing performance.

Nut & Ferrule fitting

What Are Nut & Ferrule Fittings?

  • The Nut is the outer tightening component that compresses the ferrule when torqued.
  • The Ferrule (single-piece) is the internal sleeve that compresses onto the tubing, biting into the outer wall to form a secure, leak-tight grip.

Together, the nut and ferrule form the mechanical backbone of single ferrule tube fittings, enabling safe and vibration-resistant connections — without the need for welding, soldering, or sealant.

Key Features of PE-LOCK Nut & Ferrule Sets

  1. Leak-Proof Grip – Ferrule compresses precisely onto the tube without distortion
  2. High Torque Strength – Nut ensures consistent compression and alignment
  3. Reusable & Replaceable – Easy disassembly and repeat use
  4. Material Flexibility – SS316, SS304, Brass, Monel, Inconel, Hastelloy
  5. Available for All Fitting Types – Compatible with all PE-LOCK tube fittings
  6. Fully Interchangeable – Matches Swagelok®, Parker®, and other global specs
