The brush features a brass bristle construction over a brass core, delivering adequate scrubbing action without damaging softer metal tube walls. At 11\/16 inches in diameter and 6-1\/4 inches overall length, with a brush scrubbing length of 4 inches, this tool fits standard cleaning tasks on HVAC heat exchangers, refrigeration tubing, plumbing fittings, and condensate drain lines. The male connection end accommodates standard brush extension rods. It is a hand-tool item suited for plumbers, HVAC technicians, and refrigeration service professionals.\u003c\/p\u003e\u003cp\u003eThis tube brush is used wherever tube interior surfaces require mechanical cleaning prior to brazing, soldering, or inspection.

Before brushing, ensure the tube or system is depressurized and any refrigerant or fluid has been properly recovered or isolated per applicable codes. Avoid forcing the brush into undersized bores, as overloading the spiral can deform the stem. Replace the brush when bristles show visible wear or splaying to maintain effective cleaning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Scrubbing Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction Type\u003c\/strong\u003e: Double Stem \/ Single Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 93619\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51538987712818,"sku":"93619","price":22.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a702ee87248193926fcf558b01e18b84.jpg?v=1785831908","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93619-tube-brush-11-16-in-brass-bristles","provider":"Voomi Supply","version":"1.0","type":"link"}
