The head valve piston is a critical internal part that controls air flow and pressure cycling within the tool's drive mechanism. When this component wears or fails, the tool loses consistent driving power or stops cycling altogether. Licensed technicians and experienced repair techs install this part during routine rebuild service or as a corrective repair on tools showing inconsistent actuation.\u003c\/p\u003e\u003cp\u003eThis piston is suited for use in pneumatic nailers and related MAX power tools that rely on a head valve assembly for cycle control. It is intended for professional repair applications where OEM-spec components are required to restore proper tool function. Installers working in construction, framing, or finish trades who depend on MAX pneumatic tools for production use will find this a necessary service part.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM replacement head valve piston for MAX pneumatic tools\u003c\/li\u003e\n\u003cli\u003eRestores proper air cycle and drive consistency when worn piston causes tool failure\u003c\/li\u003e\n\u003cli\u003eDesigned to match original factory dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eSupports professional-grade rebuild and repair workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement piston for MAX pneumatic power tools requiring head valve assembly service.

Disconnect the tool from the air supply and relieve all internal pressure before disassembly. Refer to the MAX service documentation for the correct disassembly sequence and reassembly procedure for the head valve assembly. Reuse of worn seals or o-rings during piston replacement is not recommended.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Head Valve Piston\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: kn12656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAX","offers":[{"title":"Default Title","offer_id":51200309952818,"sku":"KN12656","price":75.08,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/max-kn12656-head-valve-piston","provider":"Voomi Supply","version":"1.0","type":"link"}
