ACDelco thread sealant 1.69 oz — GM OE anaerobic pipe sealant, temperature and solvent resistant

ACDelco GM Original Equipment 10-2024 Thread Sealant is an anaerobic thread-locking and sealing compound in a 1.69 oz tube formulated to seal and lock metal pipe fittings while still allowing disassembly with standard hand tools.

This OE-grade thread sealant is the same formulation used or validated by General Motors for production and service applications. It is designed for use on common automotive and industrial materials including aluminum, steel, brass and plated metals. The compound cures anaerobically—hardening in the absence of air—and provides temperature and solvent resistance suitable for many fluid and gas line connections. Cure time varies with temperature and the metal substrate, so working conditions can affect handling time.

How does this thread sealant perform on different metals?

ACDelco's formula bonds to a variety of metals commonly found in automotive systems. It was developed to work reliably on aluminum, steel, brass and plated parts without the need for exotic surface prep.

• Works on aluminum, steel, brass and plated metals
• Adheres and cures anaerobically to create a leak-resistant joint
• Permits disassembly with standard hand tools when needed

What should I expect for cure time and durability?

Cure speed depends on ambient temperature, part temperature and how well the fitment excludes air. In typical shop conditions it develops handling strength within hours, with full strength achieved over 24–72 hours depending on conditions.

• Faster cure at higher temperatures and with closer metal contact
• Good resistance to common automotive fluids and solvents
• Designed for long-term sealing under normal service conditions

Can I remove fittings sealed with this product later?

Yes — this thread sealant is formulated to allow later disassembly with standard hand tools, making it service-friendly compared with permanent anaerobic adhesives. It locks components during service but is not intended to be an irreversible weld.

• Disassembly achievable with conventional wrenches and sockets
• Suitable for components that may require future maintenance
• Not intended for applications where a permanent, tamper-proof bond is required

Why use an OEM-validated sealant instead of a generic product?

OE validation means the formula meets tests and specifications used in vehicle production or approved service repair procedures. That can reduce compatibility issues with system materials and support consistent performance across applications.

• Formulation is used or validated by General Motors for GM vehicles
• Designed to meet OE materials and safety considerations for service parts
• Provides predictable behavior across typical automotive repair scenarios

Who is this for: Technicians and DIYers who need a dependable, serviceable thread sealant for automotive pipe fittings and related metal connections will benefit from ACDelco GM Original Equipment Thread Sealant. It’s aimed at users who prefer OE-validated materials for repairs and maintenance on GM vehicles or for general metal pipe-thread sealing where disassembly may be required later.

Additional note: This product comes in a 1.69 oz tube sized for workshop repairs and service operations. Follow product safety guidance and local regulations when using chemical sealants.
