Flanged Plastic Caps - Information

MOCAP FC Series Flanged Plastic Caps are designed to protect threads with and without o-rings. Protects components or fittings from moisture, dust and damage during production, shipping and storage, and can also be used as low-temp masking during painting and plating. Flanged caps are easy to assemble or remove by hand or automated equipment.

Our FC Series are available in sizes to fit:
  • Straight threads, 5/16" through 3-1/2"
  • Metric threads, M5 through M33
  • BSP and NPT threads, sizes 1/8 through 2


The FC Series is available in a wide variety of colors, including red and a "natural" semi-transparent colour which allows for visual verification of the threads or o-ring.

  • Use as Thread Protector or End Cap
  • Available For Standard Straight, Metric, and BSP/NPT Threads and Fittings
  • Flanged for Easy Removal



Many Sizes of Our Flanged Plastic Caps are Stocked for Immediate Shipment.


Most stock sizes are available in Mini-Packs when Smaller Quantities are Needed. To place an order for this product, call 0800 856 2466 or use our Contact Request Form to receive information by e-mail.
