Since its inception, the kits have been expanded for use with either Nitrogen or CO2. Why Nitrogen versus CO2. The preferred gas is Nitrogen because it's a dry inert gas that has multiple uses: purging a A\/C\u0026amp;R system, leak testing a refrigerant line, calibrating pressure controls, cleaning a condensate drain line, cleaning coils, inflating tires, unclogging a sink, operating impact tools and much more. We do not recommend that CO2 be used for purging or pressure testing a A\/C\u0026amp;R system because it may form carbonic acid within the system, causing premature equipment failure. There are certain applications where CO2 has its advantages. Because CO2 starts out as a liquid, it has a tremendous expansion rate; it is an ideal source for portable gas pressure. For example, a small 10 lb. cylinder of CO2 will yield approximately 90 cu. ft. of gas versus the same size cylinder of Nitrogen that will yield approximately 40 cu. ft. of gas. This makes CO2 ideal for clearing a condensate drain line, cleaning coils, inflating tires, unclogging a sink, operating impact tools and much more. The Sludge Sucker Kit options include a choice of high or low-pressure regulators for Nitrogen or CO2 and various carrying stands depending on tank size.

The nitrogen must be flowing to displace the oxygen inside the tubing during the brazing process, preventing internal oxidation and the resulting scale. Scale build up inside the tubing can cause blockage in the TXV and within the Air Conditioning and Refrigeration system resulting in premature failure. If the ball does not rise in the tube there is no flow of nitrogen only static pressure and oxygen is not being displaced. The NV1 must be connected to a Nitrogen Regulator with the delivery pressure set at 60 PSI to control the nitrogen gas pressure. The NV1 is protected from over pressure with a reseatable safety blow off that opens at 200+ PSI.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: Lato, sans-serif; font-size: 16px; line-height: 25px; color: #242122; background-color: #ffffff;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: Lato, sans-serif; font-size: 16px; line-height: 25px; color: #242122; background-color: #ffffff;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Uniweld","offers":[{"title":"Default Title","offer_id":41471896420426,"sku":"UNIW32","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/3549\/7290\/files\/5263866__35364.1509516101.1280.1280.jpg?v=1720530992"},{"product_id":"turbotorch-gp250-500-580-nitrogen-regulator-0386-0875-html","title":"TurboTorch GP250 500 580 Nitrogen Regulator 0386 0875","description":"\u003cp\u003e\u003cspan style=\"font-family: Arial, Helvetica, sans-serif; font-size: 12px; line-height: 20px; background-color: #ffffff;\"\u003eThe New G Series Nitrogen Purge Regulator features improved low profile design, easy to grip knob, heavy-duty gauge guard and a patented high strength alloy bonnet (nearly twice the yield strength of brass). \u003c\/span\u003e\u003c\/p\u003e\u003cul style=\"font-size: 12px; font-family: Arial, Helvetica, sans-serif; margin: 0px; padding: 0px 0px 0px 15px; color: #222222; background-color: #ffffff;\"\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003eHeavy duty steel gauge guard for added protection\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003eContoured, easy to adjust knob for precision control\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003e500 PSI Delivery\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003ePatented G Series High Strength Bonnet for added strength\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003e1\/4\" Flare Fitting\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003eSingle Stage\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 5px 0px;\"\u003eThree Year Warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"G Miller Company","offers":[{"title":"Default Title","offer_id":41471916900426,"sku":"TUR22","price":97.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/3549\/7290\/files\/9133220__26759.1507684506.1280.1280.jpg?v=1720531394"},{"product_id":"turbotorch-dp250-800-580-high-pressure-nitrogen-regulator-0386-0857-html","title":"TurboTorch DP250 800 580 High Pressure Nitrogen Regulator 0386 0857","description":"\u003cp\u003eHigh Pressure Nitrogen Regulator, DP250-800-580, 0386-0857.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUnique gauge guard for added protection.\u003c\/li\u003e\n\u003cli\u003eEasy to adjust color-coded knob.\u003c\/li\u003e\n\u003cli\u003e800 PSI delivery.\u003c\/li\u003e\n\u003cli\u003eZinc Aluminum housing cap for added strength.\u003c\/li\u003e\n\u003cli\u003e1\/4\" flare fitting.\u003c\/li\u003e\n\u003cli\u003eSingle stage.\u003c\/li\u003e\n\u003cli\u003eForged brass body.\u003c\/li\u003e\n\u003cli\u003eThree year warranty.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"G Miller Company","offers":[{"title":"Default Title","offer_id":41471916998730,"sku":"TUR23","price":129.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/3549\/7290\/files\/9133222__90349.1507729832.1280.1280.jpg?v=1720531396"},{"product_id":"diversitech-dp-1-nitrogen-purge-tool-with-adjustable-dial-html","title":"Diversitech DP-1 Nitrogen Purge Tool with adjustable dial","description":"\u003cp\u003e\u003cspan style=\"font-size: large;\"\u003eDiversitech DP-1 Nitrogen Purge Tool with adjustable dial\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: large;\"\u003eThe Nitrogen Purge Tool is a quick and easy way to purge copper pipes with nitrogen.
