Heat Traceability



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

Pressure Rating


SEALEXCEL® Fine-Lok™/Well-Lok™ Tube fittings 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 Selection


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.
Pressure ratings are from SAE J1926/3

SAE/MS Pressure Ratings for SS316

 
 
 
 
 
 
The allowable pressure for type SS316, Size 1/4"OD x 0.035 wall at 600º F (316ºC) would be
equivalent to 5100 psi x 0.85 = 4335 psi.
