The Prima Plus 28mm Compression Blanking Disc is an essential component for professional plumbers and experienced DIYers looking to securely terminate water or gas lines within existing compression fittings. These British-manufactured brass discs provide a robust, kite-marked seal that replaces the traditional olive for a lower-profile finish, though they are specifically designed for 28mm piping systems and require careful manual torque to prevent overtightening.

Yes, these are approved for use in both water and gas installations as they meet EN 1254 standards.
No, standard adjustable wrenches are sufficient to tighten the compression nut.
While they can be removed, compression seals can deform upon initial tightening; it is recommended to use a new disc if the fitting is disturbed.
It means the product has been tested to ensure it will not cause waste, misuse, undue consumption, or contamination of the water supply.
No, these are specifically designed for use within standard compression fittings.
Ensure the mating surfaces are clean and free of debris; tighten an additional quarter turn.
Check that the disc is perfectly centered in the fitting; ensure no old olive fragments are stuck inside.
To install, ensure the 28mm pipe end is clean and free of burrs if a pipe stub remains, or simply use a 28mm compression coupler to hold the disc. Place the blanking disc firmly against the pipe seat or inside the fitting body where the olive usually resides. Tighten the compression nut by hand, then apply an additional half to three-quarters of a turn with a wrench. Do not overtighten, as this may deform the brass. These discs are fully compatible with any standard EN 1254-compliant 28mm compression fitting. Periodically inspect the fitting for signs of corrosion or leakage, especially in gas applications.
