Features

Gaugeability

UNILOK tube fittings are produced in accordance with the exact and tight tolerance. Without such close tolerance, the interaction of the nut, the ferrules and the body would not be interacted properly.

Corrosion

Resistance UNILOK ferrules have the strongest corrosion resistan-ce by our own special hardening process. It has been proved in various of industrial areas for some decades.

Interchangeability

UNILOK tube fittings can be interchanged with the tube fittings which are manufactured by the international standard.

Less Torque and Anti Distortion

When the nut is tightened, both ferrules are driven forward between the nut and the body. This axial movement doesn’t transfer any torque from the fitting to the tubing when original tubing’s mechanical properties are maintained.

UNILOK Tube Fittings Installation Instruction

1. Firmly insert the tubing until it bottoms in the fitting body.
2. Finger tighten the nut.
3. Mark the nut at the 6 o’clock position, with pencil or scribe.
4. Hold the body with a backup wrench, or vice, then tighten nut.
5. 1-1/4 turns to the 9 o’clock position.
6. The above applies to all fittings from 1/4″to 1″(6mm to 25mm).
7. Fittings from 1/16″to 3/16″(3mm to 4mm), only 3/4 turn is required.

Reassembly – Simply insert tube assembly into fitting body, tighten nut to
the original position as indicated by the previous mark, then snug up slightly with a wrench.

Cleaning

UNILOK tube fittings are free from machine oils, loose particles and grease throughout the close cleaning process.
UNILOK tube fittings for oxygen enriched systems are available by the special cleaning procedure. To order, add OX to the part number.

Tubing Information

The proper selection of tubing is essential to assure maximum fitting reliability and performance. When choosing tubing material,
size and wall thickness, consider system’s pressure, flow rate, temperature, environment and compatibility with great care.

To determine allowable working pressure at elevated temperature,
multiply allowable working pressure and factors which are shown in the table.

Example: 316SS Tubing, 1/2″ODx0.049″WT at 310? AWP: 3750 x 0.85 = 3187 psig.

* MAWP: Maximum Allowable Working Pressure
* AWP: Allowable Working Pressure

Pipe End Thread Information

The end connections with the lower pressure rating is the determining factor of pressure rating for the fittings with both UNILOK tube ends and pipe thread ends .

Pressure Rating for Pipe End Thread

Tapered Pipe Threads – NPT or ISO 7/1(BSPT)

Allowable pressure ratings for male and female threads are based on ASME B31.3 at ambient temperature.
