These screws serve as the mechanical fasteners that secure the heat exchanger assembly within the heater cabinet, maintaining proper alignment and sealing under the thermal and pressure cycling demands of active pool heating systems. Correct fastener hardware is critical to preventing heat exchanger movement and maintaining the integrity of the heater's internal components. Pool and spa service technicians rely on OEM-specification hardware like the 475606 to complete heat exchanger service and replacement correctly.\u003c\/p\u003e\n\u003cp\u003eThese screws are compatible with specific Pentair heater lines, including the ETI 400 Heater series and the UltraTemp ETi Hybrid Heater series. They are typically needed during heat exchanger removal, inspection, or replacement service on residential and light commercial pool and spa installations. Having the correct OEM fastener hardware on hand avoids improvised substitutions that can lead to improper clamping, corrosion mismatch, or thread damage in the heater housing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM Pentair heat exchanger fastener hardware for accurate fit and function\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for heat exchanger service on ETI 400 and UltraTemp ETi Hybrid heater models\u003c\/li\u003e\n  \u003cli\u003eEnsures proper mechanical retention of the heat exchanger assembly during operation\u003c\/li\u003e\n  \u003cli\u003eReplaces worn, stripped, or missing screws during heater maintenance or repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Pentair ETI 400 Heaters and Pentair UltraTemp ETi Hybrid Heaters as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pool and spa service technician. Before beginning any heat exchanger service, shut off electrical power to the heater at the disconnect and close all water supply valves to isolate the heater from the system. Do not overtighten fasteners into the heater housing, as thread damage can compromise the reassembly. Follow all applicable local codes and the manufacturer service documentation for proper torque and reassembly sequence.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Heat Exchanger Fasteners for Pool and Spa Heaters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PENTAIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 475606\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENTAIR","offers":[{"title":"Default Title","offer_id":51138756313394,"sku":"475606","price":85.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531559.jpg?v=1778263053","url":"https:\/\/voomisupply.com\/products\/pentair-475606-heat-exchanger-screws-pool-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
