EPDM Synthetic Road Tube

EPDM synthetic road tube is a high quality durable rubber road tube. The EPDM synthetic holds up better under heavy traffic and is better able to withstand tube grip chafing and maintain an open air passage. Synthetic is also preferred in hot climates over natural isoprene rubber tubing as it holds up to higher temperatures.

ASTM D2000 BA 614 A14 C12 F17 Z1 Z2

Specifications:

To help further understand the specification listed above, here is a break down of each portion.
EPDM Ethylene Propylene Diene Monomer (M-class) rubber
BA BA is the material type or polymer most often used (EPDM).
B represents the material meets a critria (tensile strength, elongation, & hardness) after heat ageing for 70 hours at 100C/212F.
A represents the material 'Class' and is based on 'Oil Resistance' (volume swell).
Our specification has no requiremnet on Max Swell.
614 This is the hardness or Durometer
6 refers to a hardness of 60 duro(+/-5)
14 refers to the minimum strength at break in the value Megapascals or about 2031 psi.
A14 A is the Heat resistance indicator
1 is the testing method and duration (70 Hours)
4 is the test temperature (100C/212F)
C12 This is the percentaage of resistance to OZONE.
F17 F is the indicator for Low-Temperature Resistance
1 is the test type and duration of the test.
7 is the low temperature test point (-40C/-40F).
The following Z specifications are part of our requirements and are not part of the ASTM specification.
Z1 Cured to eliminate tackiness
Z2 Inside of road tube should be clean, smooth and free of dust, wax,
or any foreign material
