I purchased a large lot of valves from a univeristy. Many of these valves are marked as leaking or does not hold pressure. Even if the regulator is not marked, assume the regulator does function properly.

Item: Matheson L62. The sticker on the front is missing, but there is an L62 stamped on the back. I am assuming that is the model number. See photos.
