Polygon Company is the recognized world leader in the design and production of double insulation tubing for the power tool and appliance industry. With a production capacity beyond 50 million tubes annually, they competitively supply the world with "just in time" and "defect free" product. (read more)
BRIM'S BCT series of helically convoluted tubing is run to MIL-T-81914 (TFE /2, FEP /4, Tefzel /5). They provide superior chemical & electrical flexing capabilities, as helical convolutions allow smaller bend radii than straight tubings. (read more)
SH200, SH250, SH254 & SHTF tubings have excellent resistance to weathering, chemicals (oils, fuels, solvents, acids, alkalis, fluids), and fungus, are non-corrosive, low water absorption (.01%), will not burn nor support combustion, have high dielectric strength (850V/MIL dry), low die ectric constant, & a very low coefficient of friction. (read more)
Expand heat exchanger tubes into tube sheets through the direct application of high internal hydraulic pressure. Direct Hydraulic expansion with pure water produces clean joints. Minimize stress, crevice corrosion, and metallurgical changes, avoid forcing lubricant into the tube surface & prevent surface flaking or spalling inside the tube. (read more)
Rigid Polypropylene Tubes are used as center core supports in filter cartridges. Extruded cores are common in all types of cartridge filtration, whether pleated, wound or depth filter elements.
The ready availability of a wide range of product designs, and the minimal tooling costs associated with custom designs, make extruded cores a favorite for filter design engineers. (read more)
