Installed in the liquid line, it gives technicians a direct visual read on refrigerant flow conditions and moisture content, allowing fast diagnosis of system charge status and contamination. The rp18115 features a large viewing window with a color-change moisture indicator for reliable identification of wet or dry system conditions. Operating temperature range spans -40 degrees F to 185 degrees F (-40 degrees C to 85 degrees C), covering a wide range of residential and commercial refrigeration applications. Connections are 3\/8-inch FTG x FTG. Approved weight is 0.42 pounds.\u003c\/p\u003e\n\u003cp\u003eThis sight glass is suited for use in refrigerant liquid lines on residential and light commercial HVAC and refrigeration systems. It is typically installed by licensed HVAC-R technicians during system service, commissioning, or component replacement. The FTG x FTG end configuration allows direct brazing into copper tubing. The rp18115 is part of a product family available in sizes from 1\/4 inch through 1-1\/8 inch, making it adaptable across a range of system capacities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHermetically sealed housing for long-term refrigerant system integrity\u003c\/li\u003e\n  \u003cli\u003eLarge viewing window for clear observation of refrigerant flow and moisture indicator\u003c\/li\u003e\n  \u003cli\u003eColor-change moisture indicator identifies wet versus dry system conditions\u003c\/li\u003e\n  \u003cli\u003eDesigned for maximum flow and minimum pressure drop in the liquid line\u003c\/li\u003e\n  \u003cli\u003eOperating range: -40 degrees F to 185 degrees F (-40 degrees C to 85 degrees C)\u003c\/li\u003e\n  \u003cli\u003eUL\/cUL Recognized; conforms to EU Pressure Equipment Directive and UK Pressure Equipment Regulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sight glass for refrigerant liquid lines using 3\/8-inch copper tubing with FTG connections.

Recover all refrigerant and depressurize the system completely before cutting into the liquid line. The FTG x FTG connections require brazing using standard refrigeration brazing procedures; flow dry nitrogen through the line during brazing to prevent internal oxidation. After installation, pressure-test the system and recharge with the appropriate refrigerant per manufacturer and EPA Section 608 requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: FTG x FTG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e: -40 degrees F to 185 degrees F (-40 degrees C to 85 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL\/cUL Recognized; EU Pressure Equipment Directive; UK Pressure Equipment Regulation\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: rp18115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51138245951794,"sku":"RP18115","price":34.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532867.png?v=1778251523","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-rp18115-sight-glass-moisture-indicator-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
