I want to connect the bottom pistol grip of my digital air pressure
gauge with the compressor hose of my Schumacher XP2260 portable jump
starter. I need to know which Quick-connect adapters are required to
make the connection. Thanks.
Air pressure gauge with 3/8" female thread.
Schumacher XP2260 1/4" threaded air compressor hose nipple.
Your nipple appears to be 1/4" NPS (Straight) thread. I understand it
goes by the internal diameter of the pipe rather than the outer diameter
of the thread.
The nipple in Oren's photo appears to be 1/4" NPT (Tapered) Thread. It
may work with your pressure gauge, but it would be better to find the
correct nipple or an adapter between NPS and NPT. Note: If the
pressure gauge originally had a different nipple, NPT may actually be
the correct thread!
If it were me, I would remove the air compressor hose fitting and
replace it with the quick disconnect fitting to match the pressure
gauge. Then I would add a compatible nipple to the removed hose
fitting. This is essentially what I have done with a collection of air
compressors, air tanks, hoses, valves and gauges. I standardized on the
Industrial or "M" (Milton) nipples and adapters like the one in Oren's
These fittings are available in various auto supply stores, as well as
stores that sell compressors and air tools. Places like Ace Hardware,
Sears, Home Depot and Lowes.
