DISS Conversion Outlets

In the beginning...

...there were a number of competing quick-connect gas outlet designs. Over the years
manufacturing processes improved, designs changed, and standards evolved


...virtually every hospital in Canada installs DISS. Most older quick-connects are now obsolete. Parts
are no longer available.

But there is a solution.

Class 1 offers a DISS conversion kit for virtually every outlet that has ever been built!

No pipes to braze. No walls to patch. Upgrading is clean, fast and effective.

In fact, you won’t be able to tell the conversion outlet from a new outlet. All original components are replaced, right back to the copper pipe and brass block. Once installed, the gas outlet is completely restored to new condition.

And of course, just like our standard outlets, our conversions also feature the same patented
cartridge-style primary check valve and zero-maintenance secondary check valve.

Class 1 conversions.  There's nothing else like it.
