Item Information

Parflex 56DH diagnostic hose offers the best in class performance by reducing the volume of fluid in the system over -4 rubber hose. This diagnostic hose has a compact O.D., making it the optimal solution for applications where a small diameter hose is desired. It is also a very lightweight hose and, coupled with its good flexibility characteristics, allows for simplified routing and installation in small bore fluid transfer applications. It is often used as a replacement for steel tubing, which is much heavier and stiffer. In addition, it operates in temperatures up to 200°F and at 6,000 psi, withstands a minimum of 200,000 impulse cycles without leakage or malfunction.

56DH diagnostic hose is offered with a standard black jacket or a non-conductive orange design for applications where electric shock is a potential hazard for operators.
