We provide flexible sleeve for S-Flex coupling in three designs: one-piece strong, one-piece split, and two-piece with retaining ring
The one-piece split style and design provides options for applications with exclusive requirements where tiny shaft separations inhibit the installation of a one-piece solid sleeve
Pre-molded teeth along the diameter on the sleeve engage with teeth of the coupling flanges
No clamps or screws are wanted to connect the flanges with all the flexible sleeve which securely lock together beneath torque for smooth transmission of power
Torque is transmitted through shear loading in the sleeve
All 3 sleeve supplies are extremely elastic which permits the S-Flex coupling to protect connected tools from hazardous shock loading, vibration, and shaft misalignment
JE, JN, JES, JNS Sleeve Styles
These sleeves characteristic a one-piece style and design molded in EPDM & Neoprene rubber. In the case of JES & JNS Varieties, the one-piece style and design is split to provide for ease of installation and removal.
E, N Sleeve Sorts
These sleeves function a two-piece style with retaining ring. The E Type is molded in EPDM rubber and the N Type is molded in Neoprene. The two-piece design is ideal for applications in which there is difficulty in separating the shafts in the driver and driven.
H, HS Sleeve Styles
These sleeves characteristic both a one-piece reliable (H) and two-piece split
(HS) style and design and are molded of Hytrel. The sleeves in Hytrel material are designed to transmit electrical power for high torque applications. Because of the style and the properties in the Hytrel molded sleeve, the H and HS sleeves should not be used as direct replacements for EPDM or Neoprene sleeves, and can only be used with S, TF, or SC flanges.
Sleeve Elements
EPDM ?§C Unless otherwise specified, S-Flex couplings are supplied with EPDM versatile sleeves. EPDM has good resistance to commonly used chemicals and is generally 
not affected by dirt or moisture. Color is black.
NEOPRENE ?§C Neoprene presents very good performance characteristics for most applications and offers a very good resistance to chemical and oil conditions. Color is black with a green dot.
HYTREL ?§C Hytrel is a polyester elastomer designed for high torque and high temperature applications and offers excellent resistance to chemical and oil conditions. Color is orange.
