I have 3 glycerin filled, never installed/used gauges.
All bottom mount, 1/4" male pipe fittings with 2 1/2 in. dials.
1-1000 psi "Precision Industrial" gauge
1-1000 psi "Duro United" gauge
1-1500 psi "Duro United" gauge
$30 (plus shipping) for the batch, or $12.50 ea (plus shipping)
p.s. Price is in stone, or I might trade for certain Snap-On black handled rats or drivers, Proto sae large wrenches, 1/4 drive sae swivel sockets, and/or a Mac M20CW (new/like new) wrench.
Let me know!
