I have a quantity of 4 of these (as of the time of placing this listing) 5/8" fusible plugs with a 15/16" hex head. (I also have a separate listing with two 5/9" fusible plugs which have a 13/16" head.) These are presumed to be New Old Stock, acquired at the time of the close out of an area boiler manufacturer. There were several labels in the bin these had been stored in which were from ConBracCo Industries. I am presuming that these are COnBraco also. Please review the photos to check out condition. 

Buyer may purchase one or all (as many as remain available at the time buyer reviews the listing). Price is per plug.

These will ship Priority Mail, insured. I nearly always ship no later than next business day after receiving payment.

Thanks for looking!
