Swagelok Company has worked with Sandvik ® Steel, the makers of SAF 2507 super duplex stainless steel, to create a tube fi tting design for connecting SAF 2507 tube systems. This fi tting combines a patented, advanced-geometry shape for the back ferrule and a patented ferrule hardening process. The result is a Swagelok tube fi tting that can reliably grip and al on exception
ally hard SAF 2507 tube.
Swagelok SAF 2507 tube fi ttings are available in sizes from 1/4 to 3/4 in. and can be installed using simple hand tools. All SAF 2507 and 6-moly tube fi tting components are manufactured from controlled chemistry material with a minimum pitting resistance equivalent (PRE) value of 42.5. Each Swagelok SAF 2507 tube fi tting component is stamped with its material type.
Materials of Construction
Male NPT End Connections
Male NPT pipe end connections up to 1/2 in. are rated to 15 000 psig (1040 bar); sizes over 1/2 in. are rated to 10 000 psig (690 bar).
SAE/MS End Connections
SAE/MS end connections up to 1/2 in. are rated to 4500 psig (310 bar); sizes over 1/2 in. are rated to 3600 psig (250 bar), in accordance with SAE J1926.
Cone-and-Thread End Connections
Cone-and-thread end connections listed in this catalog are manufactured to API-6A “Specifi cation for Wellhead and
Christmas Tree Equipment” tolerances, Autoclave Engineers, and Butech Pressure Systems catalog dimensions. Sizes up to 9/16 in. are rated to 20 000 psig (1380 bar); sizes over 9/16 in. are rated to 10 000 psig (690 bar).
Pressure Ratings
Pressure ratings for a fl uid system are determined by the end connection or system component with the
lowest pressure rating. Ratings for the end connections listed in this catalog are discusd below.
Swagelok Tube Fittings
Swagelok tube fi ttings listed in this catalog are rated to the pressure rating of the tubing (e table below).

Elevated Temperature Ratings
Swagelok 2507 Tube Fitting and NPT End Connections
Multiply working pressure from the table above by the appropriate factor to obtain working pressure at elevated temperatures.Example: 1/4 in. tubing with 0.028 in. wall at 300°F (148°C):
The working pressure at 100°F (37°C) is 7800 psig (540 bar).The temperature factor for 300°F (148°C) is 0.85.7800 (540) ϫ 0.85 is 6630 (459).
The working pressure for 1/4 in. tubing with 0.028 in. wall at 300°F (148°C) is 6630 psig (459 bar).
Pressure Ratings for Swagelok SAF 2507 Tube Fittings ud with SAF 2507 Tubing
Pressure ratings are calculated from S values (38 700 psi [266 MPa]), in accordance with ASME B31.3, Process Piping. Pressure ratings are for metal temperatures from –20 to 100°F (–28 to 37°C). SAF 2507 tubing, fully annealed, meets ASTM A789 or equivalent. Hardness value is HRC 32 or less.For gas rvice, u tube wall thickness outside
