It is designed for installation inside the stainless steel disinfection chamber of Pentair UV55 and UV75 systems, isolating the electrical UV lamp from direct immersion in the flowing water stream.\u003c\/p\u003e\n\u003cp\u003eFused-silica glass quartz sleeve features a high-transmission physical characteristic that allows UVC light to pass through with minimal attenuation. The physical layout is structured as an elongated cylindrical tube featuring one rounded closed-off end and one open end at the top. This configuration centers the lamp inside the watertight chamber.\u003c\/p\u003e\n\u003cp\u003eImmersed within the steel water chamber, the sleeve sits against a fixed spring seat at the bottom of the vessel to absorb vibrations. The quartz sleeve operates as a passive component, with no electrical connections or moving mechanical parts. It complies with high-pressure fluid environments and is specified to withstand normal working pressures of 210 to 500 kPa.\u003c\/p\u003e\n\u003cp\u003eCleaning the quartz sleeve is required at least once per year, or more frequently in hard water conditions, to stop cloudiness, scaled deposits, and iron fouling. Servicing requires a soft microfiber cloth and vinegar or diluted citric acid cleaner. Handling precautions require the use of disposable gloves during disassembly and reassembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from clear fused-silica glass with low UVC attenuation properties.\u003c\/li\u003e\n\u003cli\u003eSits against a fixed spring seat at the base of the chamber to absorb shock.\u003c\/li\u003e\n\u003cli\u003eSeparates the dry electrical UV lamp compartment from the water flow.\u003c\/li\u003e\n\u003cli\u003eFeatures one rounded closed-off end and one open end at the top cap.\u003c\/li\u003e\n\u003cli\u003eCompatible with whole-house systems operating at pressures of 210 to 500 kPa.\u003c\/li\u003e\n\u003cli\u003eWithstands continuous water flow and temperatures of 5 to 38 degrees Celsius.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWarranty: Pentair warrants this product against defects in materials and workmanship under normal use and service for a period of one year from the invoice date.\u003c\/p\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":51091763560695,"sku":"BHML004","price":115.98,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-bhml004-high-transmission-quartz-protective-sleeve.png?v=1788173997","url":"https:\/\/foundationpumps.com.au\/products\/onga-bhml004-high-transmission-quartz-protective-sleeve","provider":"Foundation Pumps","version":"1.0","type":"link"}
