TB Woods 8HS Sleeve Coupling Insert

H (Hytrel) sleeves, designed for high-torque applications, transmit four times as much power as an equivalent EPDM or Neoprene sleeve.

Available in one-piece solid construction (H or U) or two-piece split construction (HS), these can be used only with S, C and SC flanges.

They cannot be used with J or B flanges or as direct replacements for EPDM or Neoprene sleeves.
