Yamada 640007 O'Ring 9.5mm x 2.0mm B70

Yamada 640007 O'Ring 9.5mm x 2.0mm B70

The Yamada 640007 O'Ring is a replacement sealing component measuring 9.5mm x 2.0mm and identified as a B70 O'Ring. It is designed for use in Yamada pump assemblies where a properly sized replacement seal is required to maintain sealing performance during pump operation and service.

Part number 640007 is used in Yamada air-operated double diaphragm pump assemblies and is listed as an O-Ring in Yamada parts documentation. For example, Yamada documentation for DP-series pumps identifies 640007 as an O-Ring, while compatible air-motor reseal kits can include multiple 640007 O'Rings.

For pump maintenance, using the correct part number and dimensional specification helps ensure the replacement seal matches the intended assembly. The 640007 O'Ring is therefore a practical service part for maintaining compatible Yamada pumping equipment.

Frequently Asked Questions

Q: What is the size of the Yamada 640007 O'Ring?

The Yamada 640007 O'Ring is specified as 9.5mm x 2.0mm.

Q: What does B70 mean on the Yamada 640007 O'Ring?

B70 identifies the O'Ring specification used by Yamada for this particular sealing component. It distinguishes the 640007 from other Yamada O'Rings with different dimensions or material specifications.

Q: Where is Yamada 640007 used?

Part 640007 is used in Yamada pump assemblies, including documented DP-series air-operated double diaphragm pump air-motor assemblies.

Q: Is Yamada 640007 included in pump repair kits?

Yes. Yamada 640007 is included in certain air-motor reseal kits, including kits listed for DP-40, DP-50, and DP-80-HD pump applications.

Q: Is the 640007 O'Ring interchangeable with other Yamada O'Rings?

It should not be assumed to be interchangeable. Yamada lists multiple O'Rings with different dimensions and part numbers, so the pump's parts documentation should be checked before selecting a replacement.
