A dual-valve, valve core installation/removal tee enable the removal and or replacement of a Schrader® valve insert without evacuating the refrigeration system. The use of a dual-valve valve core installation/removal tee also permits the valve core to be removed and maintenance of the HVAC system to be performed without the flow restriction of the valve core and core depressor.

Method and apparatus for valve core installation/removal

A spring clamp marker assembly is composed of interconnecting spring clamp hose markers that provide a positive and easily changeable means for marking hoses used to maintain HVAC equipment and for any other suitable application. The interconnecting spring clamp hose markers may also be used with power cables or other linear items with a generally circular cross section.
