【CTB】Changing gasket materials
The gasket included with standard products is made of silicone rubber, but it can also be replaced with gaskets made of the following materials:
CR (chloroprene rubber), EPDM (ethylene propylene rubber), FKM (fluorine rubber), NBR (nitrile rubber), PTFE (fluororesin)
※ The color of the gasket is white for PTFE and black for other materials.
※ PTFE gaskets are made of resin and have inferior airtightness compared to rubber ones. ＞
