At 48 inches long and 0.44 inches in diameter, the extension connects via a 3\/8 inches NPSM female fitting on one end and a 3\/8 inches NPSM male fitting on the other, allowing inline chaining with compatible tools or additional extensions. Fiberglass construction keeps the extension lightweight at 0.73 pounds while providing the rigidity needed to push or pull cleaning tools through tubes, coils, and pipes without significant flex. Plumbers, HVAC technicians, and maintenance professionals use this extension to service equipment in tight or recessed locations.\u003c\/p\u003e\n\u003cp\u003eThe 36048 extension is suited for both residential and light commercial applications where tube brushes or scrapers need to reach into condensers, heat exchangers, drains, or pipe runs. The 3\/8 inches NPSM thread pattern is a common standard fitting found on most tube brush and scraper handles, making this extension a practical addition to a technician's cleaning kit. It is sold individually and is well-suited for one-off service calls as well as regular maintenance routines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e48 inches overall length extends reach into deep tubes, coils, and pipe runs\u003c\/li\u003e\n  \u003cli\u003eFiberglass construction provides lightweight rigidity at 0.73 pounds\u003c\/li\u003e\n  \u003cli\u003e3\/8 inches NPSM female inlet and male outlet allow inline chaining of multiple extensions\u003c\/li\u003e\n  \u003cli\u003e0.44 inches diameter keeps profile slim for access through narrow openings\u003c\/li\u003e\n  \u003cli\u003eCompatible with tube brushes and scrapers using standard 3\/8 inches NPSM threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with tube brushes and scrapers that accept a 3\/8 inches NPSM threaded connection.

When chaining multiple extensions, ensure each connection is fully threaded to prevent separation during use. No special tools are required for assembly, but verify that the connected brush or scraper is rated for the combined extension length to avoid binding or excessive flex. Always shut off and lock out any powered cleaning equipment before attaching or detaching extension components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 3\/8 inches NPSM Female (inlet) \/ 3\/8 inches NPSM Male (outlet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.73 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SCHAEFER BRUSH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543938236722,"sku":"36048","price":32.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f0e17bf36e730fa64fb1d7c4c79c77e_07cfab43-a86a-42cf-ab78-ff7cc062365c.jpg?v=1785922431","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-36048-fiberglass-brush-handle-extension-48in","provider":"Voomi Supply","version":"1.0","type":"link"}
