The kit combines a Buna-N elastomer, carbon rotating face, and ceramic stationary seat to form a complete mechanical seal assembly. The brass seal body provides a durable, corrosion-resistant housing suited to hydronic heating system service. Licensed plumbers and HVAC service technicians install this kit during routine pump maintenance or when a worn mechanical seal causes leakage at the pump shaft.\u003c\/p\u003e\n\u003cp\u003eThis seal kit is rated for heating applications and is intended for use with VSC and VSCS series pumps equipped with a 1-3\/8 inch shaft. It is a direct-replacement kit that restores full mechanical seal integrity without requiring a complete pump replacement. To confirm correct shaft size before ordering, refer to the individual pump series documentation for the specific unit being serviced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free construction meets current plumbing code requirements for potable and heating system service\u003c\/li\u003e\n  \u003cli\u003eBuna-N elastomer provides flexibility and resistance to common hydronic system fluids\u003c\/li\u003e\n  \u003cli\u003eCarbon and ceramic seal faces deliver reliable, low-wear sealing at the shaft interface\u003c\/li\u003e\n  \u003cli\u003eBrass seal body offers corrosion resistance in wet heating environments\u003c\/li\u003e\n  \u003cli\u003eSized for 1-3\/8 inch pump shafts used in VSC and VSCS series units\u003c\/li\u003e\n  \u003cli\u003eComplete kit format simplifies field replacement without sourcing individual components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with VSC Series Pumps and VSCS Series Pumps equipped with a 1-3\/8 inch shaft.

Shut off and drain the system section containing the pump and allow components to cool before disassembly. Clean the shaft and seal cavity thoroughly before seating the new seal components to prevent premature wear. Follow local plumbing codes and the pump manufacturer service documentation for correct assembly sequence and torque procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Seal Kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElastomer Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Body Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Faces\u003c\/strong\u003e: Carbon and Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Heating\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: USSEAL186827LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 186827LF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US SEAL","offers":[{"title":"Default Title","offer_id":51524787863858,"sku":"186827LF","price":1100.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5320447c562d6b6cf63afd1c199504c9.jpg?v=1785457525","url":"https:\/\/voomisupply.com\/products\/usseal186827lf-186827lf-seal-kit-1-3-8-inch-shaft-vsc-vscs","provider":"Voomi Supply","version":"1.0","type":"link"}
