Male thread joint of sleeve

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
