Transmission OEM package sealing solution

When the design of the automatic gearbox requires very high internal fluid pressure, increase the operating temperature of the gearbox, thus increasing the risk of internal "breakdown".The gasket material produced by InterFace Solution focuses on solving such problems.To prevent gaskets from being blown out of the gearbox to resist intermittent high working pressure, we recommend the use of vb-72 and nv-519, two materials specifically designed for use with internal gaskets in gearboxes.

Technical indicators
Gasket materials Density (g/cc) Bonding agent Maximum intermittent temperature (℃) Truncated media are recommended Minimum tensile strength AMD(MPa)
MP-15 1.54 Neoprene 205 Transmission fluid 10.34
PF-6S 1.28 SBR 230 Transmission fluid 10.34
TS-9013 1.36 SBR 290 Transmission fluid 8.28
VB-72 1.47 NBR 290 Transmission fluid 15.86
NV-519 0.96 NBR 180 Transmission fluid 27.59

For the vehicle transmission, we specially recommend nv-519, which has high tensile strength and can effectively prevent the breakdown phenomenon.
For heavy duty transmissions of buses and trucks, it is advisable to use vb-72, which is not only effective in preventing blowing, but also has good high temperature resistance.As a high value product, mp-15 has excellent low flange pressure sealing performance, which is very suitable for panel application.
