Key Features
- Exact-Dimension OEM Sealing Surface — Manufactured to a precise 36mm diameter spec, ensuring full contact and compression at the rear face seal interface without distortion or gaps.

- Direct Fitment for DCA25SS Generators — Confirmed compatibility with DCA25SSAI, DCA25SSI, DCA25SSI2, DCA25SSIU-GEER, and DCA25SSIU ultra-silent generator models.
- Protects Internal Generator Components — A correctly seated rear face sealing cup prevents fluid ingress and contamination at the rear face, protecting bearings and internal rotating components from premature wear.
- Verified Part Number Fit — Part number this part is the OEM-designated sealing cup for this generator family, eliminating guesswork when ordering service parts.
A rear face sealing cup serves as a precision-fit seal at the rear face of a rotating assembly within the generator, preventing lubricant loss and blocking contaminants from entering critical internal surfaces. When this cup wears, deforms, or loses its seating integrity, it can allow oil to escape or debris to migrate inward, leading to accelerated wear on bearings and other rotating components. Replacing a worn sealing cup with the correct OEM part restores the sealing interface to its original condition and keeps the generator running cleanly and efficiently.
