The  remaining 20% air pocket helps allow for thermal expansion and  contraction as ambient temperature changes, thereby maintaining  accuracy. If the gauge were filled to 100% even the slightest  temperature change would significantly affect gauge readings as the  expanding fluid would have no place to go. To give you even further  accuracy over a wide operating range these Longacre gauges have a  Special Vent Valve on the top of the gauge. A quick turn of the knob  allows you to totally equalize internal and external pressures,  guaranteeing the best accuracy possible.\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003e\u003cem\u003eLiquid filled gauges have many advantages. But they can change readings by as much as 2-3 psi if the temperature changes...\u003c\/em\u003e\u003c\/p\u003e\r\n\u003cp\u003eAll pressure gauges - liquid filled and regular - need to be vented  to the outside to read accurately. If not vented, as the surrounding  temperature changes, they will build up pressure inside and affect the  accuracy - by as much as 2-3 psi!\u003c\/p\u003e\r\n\u003cp\u003eBut if a liquid filled gauge is vented it will leak on your hands and  in your tool box. Some manufacturers aren't aware of this and don't  vent the gauge. You then have to deal with the variation in accuracy.\u003c\/p\u003e\r\n\u003cp\u003eNow from \u003cstrong\u003eLongacre \u003c\/strong\u003ecomes the simple answer to this  problem. We have installed a specially designed pressure equalizer valve  on the top of the gauge. Before you use the gauge just loosen the knob  on top of the gauge 1\/4 turn, then hand retighten. Instantly any  temperature-caused pressure difference will be eliminated and you will  be guaranteed the most accurate readings possible.\u003c\/p\u003e\r\n\u003cp\u003eIf you have a liquid filled tire gauge prove it to yourself. Take  your gauge that has been in a cool place and in the typical range you  use. Then take the gauge and put it out in the sun for about 45 minutes,  as would happen during a race. Then re-check the tire that is still in  the cool place. You will see that the reading has changed. You know that  the pressure in the tire is the same so the gauge reading must now be  off. How will this affect your handling to have tire pressures high or  low by several psi? What's worse is that you don't know at what temp the  gauge is actually correct! It depends on the temp in the factory when  it was manufactured. You could remove the rubber fill plug on the gauge.  But then the liquid would leak out.\u003c\/p\u003e\r\n\u003c\/div\u003e","brand":"Longacre","offers":[{"title":"Default Title","offer_id":47565823541477,"sku":"52-52012 (Longacre)","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/1982\/3077\/files\/49showimage.ashx.jpg?v=1755564078","url":"https:\/\/www.425motorsports.com\/products\/longacre-lf-2-5-inch-tpg-0-45-psi-angle-ball-chuck-new","provider":"www.425motorsports.com","version":"1.0","type":"link"}
