One image saves the day!

Recently we had a customer with a late model Scania Fire Truck who thought he may need a Flare Fitting, but couldn’t be sure.

We asked him to send through an image (right) so we could ensure we supplied the right part, the first time.

After inspecting the image, we determined he infact needed a Female O-ring fitting. One question saved us sending through the wrong part!

Note: Fittings can be different without notice, however this provides a guide. If any doubt, best way is to recover refrigerant, remove fitting & confirm
