Volvo D13/Mack MP8 Injector Sleeve (w/O-Ring)

Stainless steel injector sleeve with O‑ring for Volvo D13 and Mack MP8 engines. PN 419‑6681‑05 is designed to work with Irontite’s professional sleeve removal and installation tooling for a precise, leak‑free seal in the injector bore.

Volvo D13 / Mack MP8 Injector Sleeve w/O‑Ring

The Irontite Volvo D13 / Mack MP8 Injector Sleeve is a stainless steel replacement sleeve designed specifically for Volvo D13 and Mack MP8 series cylinder heads. Supplied complete with the correct O‑ring, this sleeve restores a clean, secure sealing surface between the injector and the cylinder head.

Use it whenever you’re rebuilding a head, replacing damaged sleeves, or correcting fuel/coolant leakage around the injector bore.

Engine‑Specific Design

• Fits Volvo D13 engines
• Fits Mack MP8 series engines
• Matches the injector bore geometry for proper fit and sealing when installed with the correct tools and procedure

This sleeve is the same consumable component referenced in the Irontite Volvo D13 / Mack MP8 Injector Sleeve Professional Kit instructions (Doc PN 451‑3540‑13) and is intended for use as a service/replacement part.

Durable Stainless Steel Construction

• Stainless steel body resists corrosion and erosion in demanding diesel environments
• Maintains dimensional stability under high temperature and pressure
• Provides a long‑lasting seating surface for the injector

The robust construction helps reduce the risk of future leakage or premature sleeve failure when installed in a clean, properly machined injector bore.

Includes Correct O‑Ring

• Supplied with O‑ring to ensure a proper seal in the cylinder head bore
• O‑ring material selected for resistance to fuel, coolant, and high operating temperatures

Using the paired sleeve and O‑ring together helps prevent combustion gas, fuel, or coolant from bypassing the sleeve.

Recommended Installation Tools & Procedure

For best results, Irontite recommends installing PN 419‑6681‑05 using the Volvo D13 / Mack MP8 Injector Sleeve Professional Kit (PN 451‑6681‑00), which includes:

• Proper cleaning and re‑machining of the injector seat in the casting
• Correct application of Permatex 64000 High Heat Sleeve Retainer on the sleeve
• Full seating of the sleeve at the bottom of the casting
• Correct expansion of the sleeve tip from the combustion‑chamber side for a secure, leak‑free seal

Used together, the professional kit and this injector sleeve help deliver a repeatable, high‑quality repair.
