Had a few spare moments this morning to upgrade all gas line fittings on two older nitrogen lasers. Decided to remove all swag/ferrel connectors with quarter inch bulkhead quick release fittings. Huge improvement for connecting gas lines on these older models. Mcmaster Carr Number: 5111k734. Only had to drill a bigger opening. Also, threw in some needle valves for fine control. The Nitromite system needed a good bit of work to bring back online, repaired the high voltage pulse circuit, plus replaced the barium titanate puck, (many thanks Femtoman). Just picked up the Molectron UV24 on eBay a month ago, in amazingly clean condition! Only repairs on that one was a missing 1/4” pivoting socket nuckle for gas on/off.
