MATERIAL

Tube fittings are available as standard stainless steel 316. The raw materials used confirm to chemical requirements listed in specification below...

HEAT TRACEABILITY

Stainless steel 316 Tube fittings are heat code traceable back to the original mill heat from which it was made.

PRESSURE RATING

Tube fitting are rated for working pressure higher than the tubing recommended in tubing data table..

TUBING SELECTION

Stainless steel 304 and 316 fully annealed seamless tubing according to standard ASTM A213 or ASTM A269

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.

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 ...

Tube Fittings consist of four precision component such as Nut, Back Ferrule, Front Ferrule and Body.

CONSTRUCTION OF
FINE-LOK TUBE FITTINGS

Tube Fittings consist of three precision component such as Nut, Single Ferrule and Body.

INSTALLATION INSTRUCTION

Ensure that, the end of the tube is cut square and free from burrs without causing  undue chamfering of the tube end.

Elbows and Tees Installation procedure
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.
1.   SAE/MS positionable elbows and tees are compatible with SAE J1926 ports.
2.   ISO parallel thread positionable elbows and tees are compatible with female ports having BS 2779 threads.
NOTE :

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.

SAE SPECIFICATION

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® RECOMMENDATION

PORT CONNECTOR INSTALLATION PROCEDURE

PLUG INSTALLATION PROCEDURE

For 6mm, 1/4 and above size Tube Fittings, tighten the plug with wrench 1/4 turn from finger tight position.
For 1/8, 3/16, 3mm and 4mm tube fittings, tighten the plug with wrench 1/8 turn only.
Make subsequent connection by tightening slightly with wrench after snugging the nut by hand.

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 approximately 1/8 turn with a wrench from finger type position or 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® 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.
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.
SAE Straight thread fittings are supplied with viton 'O'-rings.
