O-ring materials
Trade Name: E0540
Durometer: 80 Shore A #Might want to consider 70-75 instead of 80 just for installation
Minimum Operating Temperature: -70 °F
Maximum Operating Temperature: 250 °F #Temperature in manifold should not be an issue
Internally Lubricated: No
Thermal Application Type: Low Temperature (< -30°F)
O-ring Specs
PH_5700_Sec4.indd (parker.com)
Needs to withstand pressure in manifold ~ 640 PSI (4.41 Megapascals)
Parameters for sizing of o-rings
High values of stretch cause the cross section to decrease, which decreases the squeeze
Parbak Backup Rings?
Should not be necessary for the purposes of the Injector
O ring calculations:
1/32 (0.04") ring:
Width of groove = 0.04+ 2 (0.2*0.04) = 0.056
Depth of groove = 0.04 - (0.2*0.04) = 0.032
1/16 (0.07") ring:
Width of groove = 0.07 + 2 (0.2*0.07) = 0.098
Depth of groove = 0.07 - (0.2*0.07) = 0.056
