Product purpose and key benefits Restores sealing and airflow performance in air compressor valve plate assemblies. This replacement set prevents leaks, stabilizes compression, and reduces the need for frequent maintenance. Copper construction resists heat and pressure, preserves seal integrity through repeated thermal cycles, and reduces risk of cracking or warping in demanding workshop environments. Stamped copper washers provide uniform contact to eliminate leakage paths in the valve plate assembly and help maintain consistent airflow and compressor efficiency. What's included Replacement valve plate gaskets and washers set 1 piece copper pad for oil or oil machine air compressor cylinder head base applications Compatible options: 47 Type, 51 Type, 65 Type (5 holes), and 95 Type for flexible compatibility Material and performance Material: conductivity copper for the gaskets, copper stamping for washers Function: Cylinder head base gasket provides a secure fit between cylinder and head assembly, maintaining compression and resisting heat/pressure stress Durability: Copper gaskets offer longlasting seal integrity under repeated thermal cycling without cracking or warping Compatibility and use Designed for air compressor cylinder head base applications, especially oil or oil machine air compressors Available in multiple type options (47, 51, 65 with 5 holes, 95) to match common valve plate configurations Practical applications (use scenarios) Routine maintenance or rebuild of a or garage air compressor to restore sealing and compression after wear Replacement during a valve plate or cylinder head in light industrial or automotive service equipment Upgrading worn or damaged gaskets in oillubricated compressor units to reduce leakage and improve tool performance Installation and handling notes Match the selected type (47, 51, 65 with 5 holes, or 95) to your compressor's valve plate pattern before installation Clean mating surfaces and remove residue before fitting the copper pad and gaskets to ensure a proper seal Check torque specifications for your compressor model when reassembling the cylinder head to avoid distortion of the copper gasket Why choose this set Directfit gasket and washer options for common valve plate types Copper construction provides reliable thermal and pressure resistance for workshop and service applications Simple parts set that addresses leakage, airflow consistency, and compressor maintenance needs without adding unnecessary components
