Workshop Warehouse Copper Sealing Washers – Metric M14 X 20 X 1.5 (HCU1420)

Description

Genuine Workshop Warehouse · Part no. HCU1420

Workshop Warehouse HCU1420 copper sealing washers are M14 x 20 x 1.5, a 14mm bore with a wider 20mm outside diameter and 1.5mm thickness, made to DIN 7603A. The extra width gives more sealing area under M14 drain plugs and fittings with a broad face, and the soft copper beds into small marks on the face.

Good to know

• Why not use a narrower M14 washer? A plug made for a 20mm washer has a wider sealing face; a narrower washer leaves part of it unsupported and is more likely to weep.
• Can copper cope with a scratched sump face? It conforms to light marks, which is why it seals well, but a deep gouge or a cracked boss needs repairing before any washer will hold.
• When should I fit a new one? Every time the plug or union comes out; tighten to the manual's torque with the washer centred, and check for drips after the first run.

Which one?

For an M14 plug with a slimmer face, the Workshop Warehouse Copper Sealing Washers – Metric M14 X 18 X 1.5 (HCU1418) suit better; an assorted box such as the Wot-Nots Washers – Copper Size Various (PMA108) covers imperial sizes.
