Ideal Tie Rod Set M12 x 1054mm 078838

The Ideal 078838 is a set of four tie rods measuring M12 x 1054mm, listed under the rods and spindles part group. Tie rods run through the section assembly of an Ideal Commercial Concord boiler and hold the cast iron sections together under compression, keeping the section seals tight and the pressure envelope sound. They are supplied as a matched set of four so the whole section stack can be re-tensioned evenly in one job.

• Visible corrosion, pitting or thinning on the rod shanks where they pass through the section assembly.
• Weeping or staining at the section joints, suggesting the rods are no longer holding the correct compression.
• Rods that will not hold torque, or that stretch and slacken off after re-tensioning.
• Distorted or cracked sections, often found alongside rods that have been over-tightened or seized.
• Difficulty removing the rods because of scale or thread damage on strip-down.

• Check the boiler model plate and GC number against the compatibility list, as the same Concord range uses different rod lengths across models.
• Compare the old rod against the M12 x 1054mm dimensions before fitting, and confirm the part number 078838 on the original component where it is still legible.
• Tie rods are normally renewed as a full set so the section stack is compressed evenly; order the quantity the job needs.
