Shopper Can it be used with the MK20-UL ("Ultra Light" Aluminum alloy) regulator? If not, is there a specific converter for the UL version?
LeisurePro S Yes, you can use this converter with the ultra light reg. It will fit, but other people who have done the same (and ScubaPro!) recommend using a lot of care and a good amount of christol lube when you screw the two piece together to avoid nicking or shredding the threads of the ultra light material with the heavier metal of the converter.
