The Multiquip 1687103310 Cylinder Head Gasket D722B is a genuine OEM replacement designed for DLW300ES, DLW300ESA, and DLW300ESA1 series diesel light welders. Sourced directly from Multiquip, this gasket delivers the exact material composition and dimensional tolerances required for a proper combustion seal on the D722B engine. Confirm your model code against the fitment list before ordering to ensure this is the correct part for your machine.
Key Features
- OEM Combustion Integrity — Manufactured to the exact compression and sealing specifications of the D722B engine, ensuring the head-to-block interface holds under operating temperatures and pressures.
- Direct-Fit Installation — Matches the bolt pattern, fire ring placement, and port openings of the original gasket, so it seats correctly without trimming or modification.
- Confirmed Fitment — Compatible with DLW300ES, DLW300ESA, and DLW300ESA1 Multiquip diesel light welder models.
- Sustained Engine Output — A properly sealed cylinder head maintains compression, protects against coolant and oil intrusion into the combustion chamber, and supports consistent power delivery to the welding system.
- Genuine OEM Assurance — Part number 1687103310 is a certified Multiquip OEM component, eliminating the guesswork of cross-referencing non-OEM alternatives for a critical engine sealing part.
The cylinder head gasket forms the critical seal between the engine block and the cylinder head, containing combustion pressure while preventing coolant and engine oil from mixing or leaking into the cylinder. On the D722B engine found in the DLW300ES series welders, a compromised or worn head gasket can lead to lost compression, overheating, white exhaust smoke, or coolant loss — all of which will affect the machine's ability to produce stable welding output. Replacing a failed gasket promptly with the correct OEM part restores engine integrity and prevents more extensive internal damage.
