Dipstick Tube to Block O-Ring Seal for LS/LT Engines

The Dipstick Tube to Block O-Ring Seal is the perfect OEM-style replacement for the lower dipstick tube seal found in GM LS and LT engines. Designed to eliminate oil leaks and prevent contamination, this precision-fit O-ring restores a tight seal where the dipstick tube meets the engine block.
Over time, the original O-ring can harden, shrink, or crack due to engine heat and oil exposure—this replacement ensures proper sealing and leak-free performance. Ideal for maintenance, rebuilds, or swaps, it’s an inexpensive yet essential part for keeping your LS or LT engine clean and efficient.
