Do you sell DN80/8? would that still be considered DIN 11851?
-
Q Do you sell DN80/8? would that still be considered DIN 11851?A I'm sorry but I am not familiar with this style of fitting. We'd be happy to send a sample of our standard DIN11851 style fittings to see if they work with your application.
Do you offer metal detectable gaskets for DIN 25?
-
Q Do you offer metal detectable gaskets for DIN 25?A Unfortunately, we do not offer this style of gasket at the moment.
What is the pressure rating
-
Q What is the pressure ratingA Maximum working pressure (according to DIN 11851) is 40 bar (DN 10 - DN 40), 25 bar (DN 50 - DN 100), and 16 bar (DN 125 - DN 150).
What size would I need if the outside is 2.75" and the inside is 2 1/2"
-
Q What size would I need if the outside is 2.75" and the inside is 2 1/2"A The closest size we can offer is DIN 50 which is 64mm on the OD and 54mm on the Inside Diameter. We do not have an exact match gasket for your specific size.
