We also build OEM-compatible seals for KSB, Wilo, Ebara, Lowara, Pentair, Hayward, AESSEAL, Vulcan, Roten and more — matched to the original dimensions and materials. Don’t see your brand? Send the pump model, a drawing or the old seal and we’ll quote a drop-in equivalent.
How OEM-compatible seals work
A compatible seal is built to the same shaft, sleeve and gland dimensions as the original, so it drops straight into the pump. We match the face pair, balance and elastomer to your service — not down-specced to hit a price — and reverse-engineer obsolete patterns from a sample. They are equivalents, not sold as genuine OEM parts.
Source OEM-Compatible Seals At Scale
Send a brand and part number, a pump model or a sample of the old seal. As the manufacturer we quote drop-in equivalents, custom and private-label seals at low minimums.
