Burks 09634 Flat Gasket 5-9/16 in OD
This is the flat gasket Burks lists as part 09634, measuring 5-9/16 in outside diameter. It seals a bolted joint between two machined castings, and it is designed to be replaced rather than reused.
A gasket is consumed the moment it is compressed. The fibres are crushed into the surface finish of both faces, and pulling the joint apart tears them. Refitting a used gasket almost always produces a seep, usually a day or two later once the joint has settled and the temperature has cycled a few times.
Both faces need to be genuinely clean before the new gasket goes on. Old material has to be scraped off without gouging the casting, and a scratch across the sealing land will leak no matter how good the gasket is.

Frequently Asked Questions
Q: How do I get the old gasket off without damaging the casting?
Soften it first, then use a plastic or brass scraper and work flat against the face rather than digging in. Steel blades and rotary wire wheels leave scratches across the sealing land that no new gasket will bridge.
Q: Can I cut my own from sheet material?
You can make something that holds pressure, but you will be guessing at thickness and compressibility. Since the thickness sets the spacing across the joint, a home-cut replacement can alter internal clearances in ways that only show up as lost performance.
Q: Should the bolts be retightened after the pump has run?
Check them once the pump has been up to temperature and cooled again. Gaskets relax slightly as they bed in, and a single even re-torque in a cross pattern often settles a joint that was weeping lightly.
Q: The joint still seeps with a new gasket. What now?
Put a straight edge across both faces. A casting that has been prised apart with a screwdriver usually has a burr or a dent on the sealing land, and that has to be dressed flat before any gasket will hold.
