D Par-Barb® Thermoplastic Fittings
Par-Barb® fttings are precision injection molded from high-strength,
chemically inert, thermoplastic materials.
The specially engineered four-barb design generates the maximum
gripping and sealing power when combined with a hose clamp. The
unique barb design requires the tube or hose to expand slightly to ac-
cept the ftting, providing a positive seal on the barbs.
Par-Barb® fttings are widely used with Parfex clear vinyl tubing, ure-
thane tubing and a variety of rubber tubing and hose. Par-Barb® fttings
meet FDA and NSF-51 specifcations for food contact.
Par-Barb® is recommended in medical, pollution control, food and
beverage applications. Other uses include irrigation, instrumentation,
reverse osmosis and deionized water systems.
Temperature range:
Black Polyethylene: -65°F (-54°C) to +190°F (+88°C.)
White Nylon: -40°F (-40°C) to +200°F (+93°C.)
Working pressures:
Par-Barb® fttings are generally used in systems where pressures
do not exceed 125 PSI.When used in excess of 125 PSI, Par-Barb®
fttings, in all sizes, should be tested by the customer in his particular
application. Operating pressures of Par-Barb® fttings are governed
by ambient and fuid temperatures, type of fuid conveyed, hose or
tubing used, clamping mechanism employed and conditions of
mechanical abuse.
