Used as a bombing chamber for helium leak testing. Vacuum connection is a 1-1/8" tube on the bottom.
Internal Dimensions
14" x 12" x 1.75" High
The cover is counter balanced with a spring and closes a micro switch when in the closed position.
Material is non-magnetic so I'm assuming it's stainless.
it comes with a machined block which reduces the internal volume for fewer parts.
The vacuum connection is made from the bottom, it's a 1-1/8" OD tube that fits a standard leak detector compression fitting.
