These Masking Straight Caps are typically used to mask studs and tube ends. They have excellent sealing capabilities due to the flexible material that they are manufactured from. Ideal applications include; powder coating, e-coating, plating, anodizing and blasting.

Although they are primarily designed fpr use as a cap, if inverted, they can also be used to plug holes.

  • Colors: Blue, Black, White, Green, Grey, Pink and Yellow
