CRIL Series

In-line rotary couplings

Tools ApplicationsIndustrial ApplicationsAgricultural Applications

Holmbury’s CRIL Series in-line rotary couplings are designed for in-line use on hydraulic circuits. Using a rotary coupling in the hydraulic line stops the hose twisting, limiting stress and increasing hose lifespan.

Carbon Steel Trivalent Materials

Features

  • Reduces torsional forces
  • Can also be used in applications that are required to rotate but not under pressure, such as hose reels
  • Spindle is carried on a roller bearing and has a low friction shaft seal that can rotate at maximum pressure with low torque
