过滤器密封件，125，丁腈橡胶 (NBR)，食品接触材料

These seals are located around the filters and hold the filters in place on the fitler plate. We recommend checking on the filters once per 1-2 weeks - the seals may be inspected during these checkups as well. A tear or a hairline cut on the seal can propagate to a bigger cut, therefore they should imply a change.
