Oil Drain Plugs & Gaskets
Sump plugs and the sealing washer that goes under them, quoted as a pair. Thread diameter, pitch and thread length are stated separately because M14 is not one size: M14×1.5 and M14×1.25 take different plugs and strip different threads when they are swapped.

Send a drawing, a sample or an OE number and we quote this part type to it. The selection data below is what the quote is built from.
What decides the price
In order of impactDiameter and pitch are two fields. A plug quoted on diameter alone will cross-thread on the wrong sump.
Crush washer, bonded seal or O-ring. The plug is reusable, the washer usually is not, and that changes what a service kit contains.
Hex head, socket head or internal drive decides whether the plug clears a splash guard without dropping the tray.
Worth checking before you order
The washer deforms once. Reusing it is the usual reason a fresh plug still drips.
Sump threads are soft and the figures differ by engine. We do not publish a torque figure without the vehicle data.

Questions
Do you supply the washer with the plug?+
Yes, quoted together. The washer grade is stated because copper, aluminium and bonded seals are not interchangeable.
Is M14×1.5 the same as M14×1.25?+
No. Same diameter, different pitch, different sump. Send the OE number or the thread gauge reading.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
