*May also be used as Plugs: to determine Outside Diameters, add approximately .06˝ (1,5 mm) to Inside Diameter dimensions.
**May also be used as Caps: to determine Inside Diameters, subtract approximately .06˝ (1,5 mm) from Outside Diameter dimensions.
† Part No. G5014 functions as a Cap for NPT 1/8˝ Hubs and a Plug for NPT 1/4˝ Hubs.
Standard color red.
- 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.
- Recommended Closures: Threaded mounting holes where Plug dimension A is at least 1% larger than the hole to be plugged. Minimum .020" (0,5 mm).
