Tapered Caps and Plugs–NPT
For
NPT
Fitting Hubs and Threaded Mounting Holes
•
HEYCaps can be used as either
caps
or plugs.
•
Because they are tapered in design and
made from highly flexible polyethylene,
they not only
fit snugly
but are readily
removable.
•
Applicable Specs: MIL-C-5501/7
(MIL-C-52078), NAS-835.
CAPS:
•
Especially recommended for use on
threaded external NPT fitting hubs.
•
Part dimensions are based on average
threaded hub fit. Before ordering in
quantity, please sample HEYCaps.
•
Recommended Closures: Threaded
hubs where Cap dimension B is at
least 1% smaller than the hub to be
capped. Minimum .020" (0,5 mm).
PLUGS:
•
Especially recommended for use on
threaded internal NPT fittings and
mounting holes.
•
Part dimensions are based on average
tapped hole fit. Before ordering in
quantity, please sample HEYCap
Tapered Plugs.
•
