Caterpillar 135-9819 Integral Seal Gasket - New OEM in Original CAT Bag

Genuine Caterpillar 135-9819 integral seal — a stamped steel carrier flange with a bonded silicone sealing bead and two-bolt mounting pattern, marked "LEFT" and "TOP" for correct oriented installation.

Application: Caterpillar OEM seal, part number 135-9819, confirmed by the number stamped into the part and printed on the original Caterpillar bag. Aftermarket and marketplace cross-references associate this number with CAT 3126-family engines and certain CAT machine flange/air-compressor sealing locations; that application has not been confirmed against OEM documentation and must be verified by serial number.

Condition: New / NOS in the original Caterpillar yellow packaging with the original distributor label. Packaging is shop-soiled from storage; the seal itself is unused, with an undamaged sealing bead and clean sealing faces.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
