Re. size o-rings: please double check the size of the grooves. We ordered the size as prescribed on the portal: 208 x 3 & 50 x 3 mm. Size is inner diameter. We got order confirmation from Eriks with the right sizes. Which o-rings are too large? 50, 208 or both? What is the difference? Apologize for the questions, we want to be 100% sure before we order new o-rings. Supply is normally from stock so timing should be no issue. Re. material: EPDM food grade is correct since it has a high temperature resistance combined with good resistance against cleaning agents. Lack of oil resistance is no issue since the product is watery. 
The other (spare) set is still at Bodec.
