HARDNESS LIMITATION

High Quality Stainless Steel tubing that is fully annealed; Seamless or Welded per ASTM A269, A213 or equivalent should be used with SUPERLOKTube fittings. The tubing must be a maximum hardness of HRB 90 or less on the Rockwell Scale,however HRB 80 is more suitable for bending and offers a greater difference in hardness to the ferrules. This difference in hardness offers more ease in assembly and better interaction between the ferrules and the tubing.

COMPATIBILITY

SUPERLOK Tube fittings are manufactured in order to be 100% interchangeable with other Tube Fittings currently on the market. SUPERLOK fully warranties the compatibility of with different manufactures provided the same strict manufacturing practices and tolerances are held by those manufactures. If possible only the SUPERLOK should be used to guarantee system quality.

GAS SYSTEM APPLICATION

SUPERLOK Tube Fittings are appropriate for Gas Systems, but the implementation of certain standards mentioned below should be adhered to just as in other systems.

Tubing Standard in Gas System
(Apply to the installation of general system)

Tubing hardness must be less than that of the ferrules.
Tubing should be free of surface imperfections, defects and round in shape.
Refer to Table 2 on page 13 for selection of the appropriate wall thickness.
(Only shaded areas should be selected for Gas Systems)
Tubing ends must be cut squarely and perpendicular to the center-line of the tubing. After the tubing is cut it must be deburred on both the inside and outside with a High quality fully sharpened deburring tool.
Follow the SUPERLOK Installation Instructions.
Do not attempt to bend the tubing after a fitting has been Installed in a fixed position.
Tubing Systems should be installed to allow for adequate expansion and contraction as well as ease of maintenance.

MATERIAL

SUPERLOK tube fitting are available as standard in stainless steel, brass, and alloy material . Straight fittings are machined from cold finished bar stock and shaped bodies from forgings Specifications for fitting materials are listed below. For special applications , contact your local distributors.

Please refer to ASME B31.3-1993 concerning the detailed information about the maximum & minimum temperature of various materials.

VACUUM, CRYOGENIC AND HIGH TEMPERATURE APPLICATIONS

SUPERLOK Tube Fittings have been tested in Vacuum, Cryogenic and High Temperatures insuring repeatable and reliable performance in the severest of Applications.

THREADS

	NPT (National Pipe Thread) Thread angle 60° Tapered angle 1°47' Manufactured by the standard of ANSI B2.1 ISO 7/1 Taperad Thread Thread angle 55° Tapered angle 1°47' Equivalent to the standard of DIN2999 BS21 (BSPT) and JIS B0203(PT). ISO 228/1 Parallel Thread Thread angle 55 Equivalent to the standard of BS 2779 (BSPP), JIS B0202 (PF). As the thread in accordance with ISO 228/1 cannot be sealed perfectly, the sealing shall be done by the following method. Use a gasket or O-Ring to seal.

	1. Bonded Washer Seal Be sealed by contacting the inclined surface of the hex body of male thread to the surface of the female thread. In case of sealing, a washer which composed of metal and elastic material is located at the center of tapered surface.

	2. Metal Gasket Seal A Metal gasket (generally copper) is sealed between the body of male thread and the surface of female thread.

	3. Metal Gasket Seal This is a method to insert a gasket into the flat surface of thread's inside. The sealing shall be completed with pushing the gasket by male thread surface.

	4. UNF Thread Thread angle 60 This is classified into UN, UNC and UNF. The standard is classified by the diameter of thread and the number of threads per inch. ASME B 1.1
