IV Cath 22g x 1" Jelco. (J&J) Catheter is the leading standard short peripheral I.V. Catheter made of FEP polymer. These FEP polymer catheters feature a thin-wall design that provides high flow rates and often allows the use of a smaller gauge device. The sharp, beveled needle tip delivers consistent, easy insertions and minimal tissue trauma. Controlled trim accuracy reduces the risk of entry problems. A translucent hub allows easy flashback visualization.
