  • 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.
  • CAPS:
    • Especially recommended for use on threaded external SAE and MIL Std.-type tube and hydraulic fittings.
    • 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 SAE and MIL Std.-type tube and hydraulic fittings.
    • 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)

*  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. G5009 functions as a Cap for SAE 1/8" Hubs and a Plug for SAE 3/16" Hubs.
†† Use Part No. G5016 for SAE 9/16-18 thread and Part No. G5020 for SAE 5/8-18 thread.
