HY-FLEX Grade C Rotary
Vibrator Drilling & Decoker

The HY-FLEX Decoker hose is used in applications that call for a flexible connection between standpipe and swivel for pumping mud at a very high pressure in oil drilling and exploration. It is also ideal for refinery decoker service when coupled with HY-FLEX Full Flow Couplings. This hose features high strength spiral steel wire reinforcement which provides a very flexible connection capable of withstanding high pumping pressures. The CR cover and NBR tube offer excellent resistance to heat, oil, drilling muds, abrasion and weather.

Technical Overview

Cover Color ■ Black

   Lengths for Coupled Assemblies hose are measured
   overall from threaded end to threaded end of the couplings
   Lengths tolerance is ± 1% for the over-all length of the
   hose or hose assembly.
Couplings ■ Highflex special internal expanded and swaged-on couplings
   for hose made to length. 3″ male API line pipe thread on
   2-1/2″ size hose. 4″ male API line pipe thread on 3″ and
   3-1/2″ size hose.
   Flanges or Hammer Unions can also be added to couplings
