General Construction
Construction standards may vary between
specific thermoplastic hoses.
Parflex bonds hose layers to provide maximum kink resistance and flexibility
through a wide range of applications. Specific braid materials, wire reinforce-
ments, spiral reinforcements and distinguishing features are clearly called out with
each hose product. Perforated and non-perforated hoses are available
ii-
based on application.
WITH NOTED EXCEPTIONS, Parflex hoses are engineered and manufactured to a 4:1 burst
pressure to working pressure ratio that follows SAE design standards. Never operate a hose
beyond its published working pressure. [Working Pressure x 4 = Minimum Burst]
