Did the trick!

This is a really hard to find item and I appreciate you stocking it. I needed it to connect a UK G35 connector on a Perrin & Rowe Hot water dispenser to a ReadyHot heater unit via an undercounter RO filter system. Needed to cascade a few adapters but saved over $500 not having to purchase the P&R heater. Thanks again.
