St. Clair Rubber “Low Pressure” Helmet linerEntry/Object ID
2017.1.51Description
There were several attempts at designing a suitable liner for the M1 helmet, one of these designs came from the Marysville based St. Clair Rubber Company.
The St. Clair liners were made using a three-step process and were cured in a low-pressure steam press and each liner took in excess of 10 minutes to cure, which slowed production.
Another problem with them was the fact that they were prone to shatter when impacted, not a good trait for a combat helmet to have.
St. Clair liners are darker in color and have a more pebbled texture than the high-pressure liners.
They are normally marked with a yellow ink stamp “SC” inside the dome.
450,000 were made 1942-1943
