James Walker Townson <strong>Rubber</strong> Comflex ® <strong>Expansion</strong><br />
Joint Type 45<br />
Type 45 is a low corrugated rubber Comflex ® <strong>Expansion</strong> Joint with good<br />
noise absorbing characteristics and high expansion absorption<br />
in all three planes. Because of its low corrugation, with<br />
outstanding noise and vibration absorbing qualities as well<br />
as high expansion absorption in all directions a very low<br />
adjusting force is possible.<br />
TYPE 45<br />
Design<br />
Low two-corrugated rubber bellows with nylon-reinforcing<br />
inserts and integral sealing bead (therefore - self-sealing<br />
without additional gasket) for accommodating three-piece<br />
unions (DIN EN 10226 conical). Available with or without<br />
solid-ring between the corrugations externally.<br />
Connections<br />
Type 45 red both sides: With malleable cast iron, galvanized unions<br />
Type 45 blue both sides: With red brass/brass or high-grade steel<br />
unions<br />
Type 45 blue with drinking water approval acc. to KTW<br />
