Anerobic, RTV, and standard sealants are all used for various repairs.
RTV (room temperature vulcanizing) sealers are used when a non-rigid part is attached to a rigid part (e.g. oil pan to engine block).
Typical RTV sealers would be Permatex High Temp, Ultra Copper, Ultra Black, or Loctite 599.
Anerobic (gasket eliminator) sealants are used where two rigid parts are being assembled. This type of sealant cures in the absence of air. Typical anerobic sealers are Loctite 510 and 518.
Standard type sealers are used primarily as gasket dressing or thread sealants. Typical examples would be Permatex #2, or Perfect Seal spray sealer.
Thread locking sealants are frequently recommended for fasteners subject to heat and vibration. Recommended products are:
– Loctite 242 for all purpose use
– Loctite “Stud and Bearing Mount” for semi-permanent attachment
