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 Control procedures approved to ISO 9001-2000 quality management systems to provide zero leak, Torque free seal in instrumentation and process tubing.

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.

PIPE THREAD INFORMATION

Pipe fittings are available with NPT/BSP/ISO and SAE/MS straight thread.

ORDERING INFORMATION

The part Number describes completely assembled Fine-Lok / Well-Lok  Tube fittings.
