S-Flex Sleeves
Flexible sleeves for S-Flex couplings can be found in 3 components (EPDM, Neoprene, and Hytrel) and in three basic types: one particular piece reliable, one-piece split, or two piece
JE, JN, JES and JNS Forms
JE and JN Style sleeves characteristic a one-piece strong layout
JES and JNS Kind sleeves function a one-piece split design and style
JE and JES Form sleeves are molded in EPDM materials
JN and JNS Style sleeves are molded in Neoprene materials
E and N Kinds
E and N Sort sleeves function a two-piece design with retaining ring
E Form sleeves are created from EPDM material and therefore are readily available in sizes 5-16
N Type sleeves are made from Neoprene materials and therefore are offered in sizes 5-14
Two piece sleeves are best for applications wherever little shaft separations inhibit the installation of the 1 piece sleeve
H and HS Forms
H and HS Variety sleeves are made for high torque applications, transmitting about four instances as substantially power as an equivalent EPDM or Neoprene sleeve
Hytrel sleeves are available inside a one-piece reliable (H) or two-piece split (HS) building
Hytrel sleeves may be used only with 
S or SC flanges and may not be applied with J or B flanges
Hytrel sleeves should really not be employed as direct replacements for EPDM or Neoprene applications
H and HS Type sleeves are available for sizes 6-14 (sizes 13 and 14 can be found in HS only)
