Designed for smaller hose systems, these couplings may be used for hose I.D.'s of 1/4" - 1" and come complete with factory assembled stem and ferrule combination. Can be Swaged or Crimped. Other hose O.D.'s available.

High Pressure Couplings
Use these couplings for services requiring a fitting which will withstand extremely high pressures (up to 3,000 PSI) and severe operating conditions, such as on small and medium size drilling rigs, used for Slim Hole, Core Drill, Workover, Seismograph, Water Well, Blast or Shot Holes, etc. These extra long, rugged fittings are machined from seamless pipe and tubing with specially designed serrations. The mating ferrules are machined from heavy wall material incorporating matching serrations and rows of set screws for better coupling retention. These couplings are shipped with matching ferrules. Please provide hose O.D. when ordering for properly sized ferrule. Make sure both ends of the hose are measured for O.D. Must be swaged with 50 Ton or 100 Ton Ram.
