This O ring provides a sealing function within the engine assembly on Land Rover vehicles, preventing oil or coolant leakage at mating surfaces such as oil galleries, coolant passages, or component housings. Correct fitment is essential as a degraded or incorrectly sized O ring can result in fluid loss, contamination between circuits, or overheating. Using the correct replacement ensures a reliable seal without distortion or premature compression set. Key Features Circular elastomeric seal designed to seat within a machined groove and compress under assembly load Must be fitted dry or with a light application of clean engine oil depending on the sealing application Manufactured to OEM dimensions to ensure correct compression ratio within the mating groove Inspect the seating groove for wear or damage before installation; replace any associated gaskets or seals disturbed during access Vehicle Fitment This O ring fits the Range Rover Classic, Series 1, Series 2 and 2A, and Series 3 as an engine parts application.
