SEALEXCEL Fine-lok/ Well-Lok
Tube fittings have been carefully designed and manufactured
with continuous research and development backing to very stringent
tolerances under rigid quality controlled procedures approved
to ISO 9001:2000 quality management systems to provide zero
leak, Torque free seal in instrumentation and process tubing.
SEALEXCEL Fine-lok/ Well-Lok Tube fittings ensures maximum safety and reliability due to Tests carried out such as High pressure, impulse, vibration, vacuum, temperature, pull out and burst pressure. |

|
| PRESSURE RATING : |
|
|
SEALEXCEL Fine-lok/ Well-Lok Tube fitting are rated for working pressure higher than the tubing recommended in tubing data table as shown below. However, tubing should not be used above its maximum allowed working pressure.
|
|
|
|
| TUBING SELECTIONS: |
|
Stainless steel 304 and 316 fully annealed seamless tubing according to standard ASTM A213 or ASTM A269 or equivalent, are suitable for use with Fine-lok/Well-Lok tube fittings.
The tubing should be compatible with the process fluid, pressure and temperature.
For good performance of Fine-lok/ Well-Lok tube fittings, the tubing should be reasonably round, free from nicks, scratches, the surface finish should be good and tube ends are squarely cut and must be free from burrs.
The hardness of tubing as desired is 80Rb; the maximum allowed by ASTM is 90Rb.

GAS SERVICE : |
|
|
Extra care must be taken while selecting tubing for gas application, In order to achieve a gas-tight seal, ferrules in instruments fittings must seal any minor surface imperfections.
The thick walled tubing helps the ferrules to overcome minor surface imperfections.
SEALEXCEL recommends the following minimum wall thickness of tubing for gas application.

PIPE END NPT and ISO PRESSURE RATINGS : |
|
|
Fitting that has both tube and pipe thread ends can have different pressure ratings. The pipe end pressure ratings chart given below for SS316 shows the pressure ratings for male and female pipe thread ends.
Working pressure is calculated on ANSI code for pressure piping B31.3 basis.

INSTALLATION INSTRUCTIONS : |
|
|
Fine-lok/ Well-Lok Tube Fittings : |
|
|
1. Ensure that, the end of the
tube is cut square and free from burrs without causing undue
chamfering of the tube end.
2. Loosen the fitting Nut.
3. Insert the tubing into the fitting assembly resting it firmly on the internal shoulder of the fittings.
4. Finger tighten the nut.
5. A) Tighten the nut with a wrench 1 1/4 turns from the finger tight position. For the tube fittings size 6mm / 1/4" and above. |
|
|
|
|
|
| INSTALLATION INSTRUCTIONS : top |
|
|
B) Tighten the nut with a wrench 3/4" turn from the finger tight position for the tube fittings size 4mm / 3/16" and below. |
|
|
|
|
|
|
|
SEALEXCEL RECOMMENDATION : |
|
|
For high pressure application :- |
|
|
Due to variation in the tubing diameter SEALEXCEL recommends the following instructions for safety and excellent performance of high pressure applications.
1. After insertion of tubing to the fittings assembly, tighten the nut with a wrench until the tubing does not rotate freely by hand.
2. Further tighten the nut with a wrench 1 1/4 turns to have a firm and safe grip. |
|
|
| SEALEXCEL RECOMMENDATION : top |
|
|
REASSEMBLY INSTRUCTION : |
|
|
SEALEXCEL Tube fittings may be assembled and disassembled repeatedly. The following instructions should be carried out to reassemble the fittings.
1. Firmly insert the tubing end with the previously set ferrules into the fitting body and tighten the nut to a hand-tight condition.
2. With a wrench, tighten the nut until a sharp condition rise in torque is felt, then simply snug with wrench.
|
|
|
|
|
REASSEMBLY INSTRUCTION : |
|
|
Elbows and Tees Installation procedure :- |
|
|
|
|
|
|
|
1. Lubricate the 'O' -ring with lubricant compatible with the system fluid and 'O"-ring material.
2. Turn the fittings into the straight thread port until the metal back-up washer contacts the face of the port.
3. Position the fittings by backing it out, (not more than one turn).
4. Hold the fittings in position and tighten the lock nut until the washer contacts the face of the port.
|
|
|
|
|
NOTE :
1. SAE/MS positionable elbows and tees are compatible with SAE J1926 ports.
2. ISO parallel thread position able elbows and tees are compatible with female ports having BS 2779 threads.

Face Seal O"-Ring Fittings: |
|
|
Installation Procedure :
The O"- ring requires a smooth, flat seating surface, this surface must be perpendicular to the axis of the threads.
1. Turn the O"- ring seal fitting in the port until finger tight.
2. The "squeezing" effect on the O"- ring can be felt during the last 1/4 turn. |
|
|
|
|
Face Seal O"-Ring Fittings: |
|
|
SEALEXCEL SAE straight thread 'O"- ring fittings are designed and manufactured to meet SAE standard as follows-
1. Male or External fittings End (Dimension: SAE J514)
2. Straight thread SAE J475 (Equivalent to ANSI B1.1 or ISO R725)
3. Female or Internal Straight thread (Port : SAE J1926)
SEALEXCEL Tube fittings with SAE Ends Straight thread
SAE Straight Thread 'O'-Ring seal fittings are designed and manufactured to SAE standards defined below for use in many different application including hydraulics and natural gas vehicles.

PORT CONNECTOR INSTALLATION PROCEDURE : |
|
|
1. Remove nut and ferrules from the first of two Fine-lok / Well-Lok ports to be connected.
2. Slip nut only on port connector over machined ferrule.
3. Insert connector into first port and snug up nut by hand. Tighten the nut with wrench 1/4 turn only, for 1/8, 3/16, 3mm and 4mm tube fittings, tighten the nut 1/8 turn from finger tight position, subsequently connections are made snugging the nut by hand.
4. Insert other end of port connector into Fine-lok/Well-Lok port 2, and tighten the nut 1 1/4 for 1/8, 3/16, 3mm and 4mm tube fittings tighten the nut 3/4 turn from finger tight position.

|
|
|
|
PORT CONNECTOR INSTALLATION PROCEDURE : |
|
|
Tighten plug with wrench 1/4 turn from finger tight position, for 1/8 ,3/16, 3mm and 4mm tube fittings, tighten 1/8 turn only.
Make subsequent connection by tightening slightly with wrench after
snuggling the nut by hand.
