  • Product description

Double card sleeve connector


Double sleeve joint provides all-metal seal, non-elastic seal element, sealing is more reliable


SMYTIK double sleeve joints are stronger than any applicable pipe


Meet the industry standard, suitable for various standards of pipe


The hardness of stainless steel pipe is recommended to be less than 85HRB


Sizes from 1/16 to 2 in., 2 mm to 50 mm


SMYTIK double card sleeve joint materials are stainless steel, brass, carbon steel, aluminum, nickel copper alloy, Hastelloy alloy, Inconel alloy and so on


SMYTIK's specially treated rear sleeve ensures a safe and reliable seal


Thread internal silver plating treatment to prevent bite, multiple disassembly


Reliable seal can be used in high pressure, vacuum and vibration applications



Performance and Testing


Hydraulic seal test (1.5 times working pressure): No leakage


Repeated installation test (10 times) : No leakage


Maximum static pressure test (4 times working pressure): No leakage


Vacuum test (1 x 10 ⁻ ⁴ mbar or larger) : leakage rate is less than 1 x 10 ⁻ ⁸ mbarl/s


Aerostatic pressure test (nitrogen at 1.5 times working pressure) : No bubbles


Hydraulic vibration and pulse testing (pulse frequency 0.5Hz to 1.7Hz, vibration frequency 23 Hz to 47Hz) : No leakage


Thermal cycle test (-25℃ to +80℃ alternating temperature): No leakage


Pneumatic pressure vibration test (45 hz frequency cycle 20 x 10 ⁶) : no failure


Fire resistance test (according to BS ISO 19921) : No leakage


Corrosion resistance test (salt spray test 168 h): no rust spot


Deep water test (equivalent to 3048 m deep water) : No leakage
