Features:
* Twin ferrule fittings provide metal-to-metal seal connections, non-elastomeric seals for leak-free connections
* Hikelok twin ferrule fittings are designed to have a maximum allowable working pressure that is higher than that of any tubing
* Industry standard design for all instrumentation grade tubing
* Stainless steel tube harderness: the hardness of the tube shall be not greater than 85 HRB
* Available in sizes from 1/16 to 2in and 2 mm to 50 mm
* Hikelok fittings materials include 316 stainless steel, steel, brass, aluminum, nickel-copper, Hastelloy C, 6Mo, Incoloy 625 and 825
* Hikelok special treated back ferrule is to provide secure
* Silver coated threads to reduce galling
* Leak-proof joints capable of satisfying high pressure vacuum and vibration applications
Performance
* Hydraulic proof pressure test (1 .5 times the maximum permissible working pressure): no leakage
* Dismantling and reassembly test (dismantle 10 times): no leakage
* Minimum hydrostatic pressure test (4 times the maximum permissible ambient pressure rating): no leakage
* Vacuum test (1 x 10-* mbar or greater): the leak rate less than 1 x 10-*
* Maximum static gas pressure test (with nitrogen gas to 150% of pressure rating): no visible bubbles
* Hydraulic impulse and vibration test (the pressure impulses at between 0.5 Hz and 1.7 Hz and the vibration at between
23 Hz and 47 Hz): no leakage
* Thermal cycle test (ambient to +80 "C and then to -25 "C with a hydrostatic pressure): no evidence of leakage
* Pneumatic pressure vibration test (The frequency of vibration shall be set at 45 Hz and complete 20 x 10* cycles): without failure
* Fire test (in accordance with BS ISO 19921): no leakage
* Corrosion resistance test (the duration of exposure at least 168 h): no visible evidence of corrosion
* Deep water submersion test (equivalent to 3048 m of sea water): no helium detected
