WFCYQ Gasket Set for Sanborn 130/165, Replaces 046-0151 & 046-0152
The WFCYQ gasket set is designed to replace both head and base gaskets on Sanborn 130 and 165 models. It covers the valve plate to head gasket (046-0151) and the valve plate to cylinder gasket (046-0152). Best for DIY repairs or small shops that need a direct replacement kit aligned with original part numbers. This kit supports re-sealing critical interfaces to prevent air leaks and loss of compressor efficiency. Use this if your model matches Sanborn 130/165 and you need to replace both gaskets at once.
Best for: Home repair enthusiasts and shop technicians targeting Sanborn 130/165 units with identified gasket part numbers. Better for completing a complete gasket refresh in one step. Caution: Verify model compatibility before purchase to avoid misfit parts.
Indanpow Air Compressor Gasket Set Fits 54571609 97330658 SS3 SS4
The Indanpow gasket set is tailored for SS3 and SS4 air compressors, including head gaskets to support effective sealing under typical pump pressures. The kit’s stated function is to create a reliable seal that minimizes air seepage and maintains pump performance. It is a solid choice for those with SS3/SS4 configurations looking to simplify replacement with a single head gasket set. Best for: Professionals working on SS3/SS4 repairs and hobbyists replacing aging gaskets. Caution: Confirm the exact model code to ensure compatibility with your unit.
PATIKIL Air Compressor Head Gasket Kit (5 Pack)
This five-pack from PATIKIL uses copper gaskets sized for 65mm cylinder heads. It includes precise dimensions (86mm x 86mm with 62mm hole distance) and aims to deliver durable, long-lasting sealing. Copper gaskets often withstand higher temperatures and pressures, which can benefit heavier-use compressors. Best for: Repairs on compressors requiring a 65mm diameter copper gasket. Caution: Copper can be less forgiving on misalignment; ensure clean mounting surfaces and correct orientation during installation.
PATIKIL Pad Air Compressor Valve Plate Replacement Kit (3 Set)
This 3-set PATIKIL kit covers upper, middle, and lower cushions designed to fill irregular gaps and seal effectively. The packaging notes a paper-based gasket material intended to seal against internal gases and maintain compressor pressure. Best for: Replacing worn head base and sealing gaskets where irregular surfaces exist. Limitation: Paper-based gaskets may be less durable in extremely oily environments; ensure surface cleanliness before installation.
WFCYQ 5140118-80/79 Z-CAC-291-1, Gasket Filter Kit
This gasket filter kit includes a head gasket and cylinder gasket with a seal between the valve plate and head. It is marketed for Craftsman and various other air compressors, with dimensions noted for compatibility. Best for: Upgrading or restoring seals in compressors that match the 5140118-80/79 and related models. Caution: Confirm exact model match; part numbers and dimensions can vary across brands.
3 Set for Central Pneumatic Parts (Harbor Freight)
This kit provides three sets of central air port gaskets and includes stainless steel reed valves with aluminum valve plate gaskets. It emphasizes correct installation lubrication during replacement to prevent valve rupture. Best for: Central Pneumatic and Harbor Freight units requiring multiple reed valves and gasket pairs. Caution: Proper grease application is essential during lower valve installation to avoid premature failure.
WFCYQ 5140118-37 / K0159 Gasket Set
This WFCYQ kit combines K-0159 and KK-4275 components, including head-to-valve plate and cylinder gaskets along with oil pan gaskets, vent filters, and several screws. It targets 2nd generation oil-lubricated twin cylinder air pumps. Best for: Upgrading multiple seals in compatible Craftsman/Devilbiss/Porter Cable systems. Limitation: The kit is broad in scope; verify exact model compatibility to avoid extraneous parts.
Buying Guide
Key purchase considerations help buyers tailor their choice to the compressor’s design and maintenance needs.
- Model compatibility: Check your exact model and part numbers (for example 046-0151/046-0152 or 5140118-80/79) to avoid misfits.
- Material and durability: Copper gaskets offer strong sealing for long-term use but require careful alignment. Paper seals provide gaps-filling capability but may wear faster in oily environments.
- Seal interfaces: Determine whether you need a head-to-cylinder gasket, valve plate to head, or combined sets for a full refresh.
- Installation notes: Some kits require lubrication during valve installation and careful surface cleaning for proper sealing.
- Number of pieces per kit: A 5-pack or 3-set kit can save time when multiple seals are aging; assess whether you need a single replacement or a multi-piece kit.
- Compatibility range: Some kits mention compatibility with Craftsman, Devillbiss, Porter Cable, Harbor Freight, and other brands; confirm your unit’s manufacturer and series.
Frequently Asked Questions
- What is the purpose of a head gasket in an air compressor?
It seals the cylinder head to the block, preventing air leaks and maintaining compression for efficient operation. - How do I know which gasket kit I need?
Verify model numbers, cylinder diameter, and interface requirements (head-to-cylinder, valve plate to head, etc.). - Is copper better than paper for head gaskets?
Copper gaskets provide durability and heat resistance; paper gaskets can fill irregular gaps but may wear sooner in oily environments. - Can I replace gaskets without disassembling the whole unit?
Replacement typically requires disassembly to access the head, valve plate, and cylinder; follow manufacturer instructions precisely. - Should I replace all gaskets at once?
Replacing the head gasket, cylinder gasket, and valve plate gaskets together reduces the chance of future leaks and ensures better performance. - Are there any installation tips?
Clean all mating surfaces, align holes and seals carefully, and reinstall fasteners to the recommended torque to avoid leaks.
