The Intru-Lok fitting is a flareless fitting that consists of a body, a one-piece precision machined ferrule, and a nut. On assembly, the ferrule "bites" into the outer surface of the tube with sufficient strength to hold the tube against pressure. The ferrule also forms a pressure seal against the fitting body. Intru-Lok fittings allow the fitting assembler to visually inspect the bite quality, thus significantly minimizing the risk of improper assembly and related service problems. Intru-Lok fittings are routinely used in markets, such as: Machine tools, chemical, oil refineries, paper making, thermoplastics processing, air and lube lines, pilot lines, panel boards, etc.

1. Bite Type — The Intru-Lok ferrule bites into the tubing assuring a safe, leak free, vibration proof connection.

2. Tube Types — Intru-Lok fittings are equally effective on copper, aluminum, brass, nylon, teflon, PVC, polyethylene and polyurethane tubing.

3. Pressure Rating — Intru-Lok is a 1500 psi fitting in all sizes through 1/2".

4. Material — Intru-Lok is manufactured from brass and all shaped fittings are machined from forgings for additional strength.

5. Temperature — Intru-Lok is suitable for use from -65° F through +400° F.

6. Make-up — The Intru-Lok fitting requires low assembly torque for make-up; joints can be disassembled and reassembled many times to facilitate system maintenance.

7. Availability — Intru-Lok fittings are available from stock in 15 standard configurations and sizes from 1/8" through 1/2". An international network of stocking distributors provide immediate delivery.

8. Captive Ferrules — Ferrules for Intru-Lok fittings are retained within the nut. This snap in feature permits the ferrule to be inserted or removed from the nut under finger pressure but the ferrule remains in place for fitting assembly.

9. Closer Tube Bends — Tube bends can begin adjacent to the end of the ferrule allowing tighter and neater installation.
