Flexelene™ FX tubing is designed for use with barbed fittings and is compatible with most standard barb sizes. The inside diameter of the tubing is sized so that Eldon James fittings fit easily into the tubing. FX tubing and FXAG antimicrobial (protected) tubing are recommended for use with barbed fittings only.
Flexelene™ CFX tubing is designed for use with compression or push-on style fittings. CFX and CFXAG antimicrobial (protected) tubing is sized so that the outside dimension (OD) of the tubing is compatible with push-on fittings. This type of fitting seals with an O-Ring against the tubing’s outer wall. Eldon James single barb fittings can be used with Flexelene™ CFX tubing; however, use of a lubricant (glycerine, water, soap, alcohol etc.) may be necessary to facilitate insertion.
