Description
Application and Usage scope
Application
Select the material according to the type of liquid
Gaskets for various pipe flanges and equipment
Usage scope
Usage temperature range: depends on the rubber material
Maximum working pressure: 1.0 MPa
Type
TOMBO No. Product name Structure 1050 RUBBER CUT GASKET A product in which various rubber sheets are punched into gasket shapes 1051 CLOTH-INSERTED RUBBER CUT GASKET A product in which various rubber sheets that are reinforced with polyester fabric are punched into gasket shapes
*TOMBO No.1051 is reinforced with polyester fabric, and so there is less flange protrusion. However, in the case of a gas seal, it is inappropriate to use TOMBO No.1051 because it is susceptible to ingress and leakage.
