CASTROL Braycote 631 RP

Explanation

Castrol Braycote ™ 631 RP is a smooth, buttery, off-white NLGI # 2 lubricant based on perfluoroether oil. This oil

it is fireproof and chemically inert in general. Thermally stable alone or in the presence of oxygen,

it has extremely low volatility and little tendency to generate deposits. In addition Braycote 631 RP exhibits excellent

lubrication properties, good dielectric properties and shear stability. Castrol Fluoroclean ™ X100 and Castrol

Fluoroclean ™ can be used to remove this lubricant. For information about these products, see their data sheets.

Application

Braycote 631 RP is designed for static or dynamic service in the presence of fuels and oxidizers. This has been used

as Gears, ball and roller bearings, electrical contacts and tooth and elastomer sealant. It is especially useful as a

lubricant in abrasive or oxygen (LOX/Gox) service and as a plug valve lubricant. Compatible with this product

concentrated acids and bases and will not hydrolyze or oxidize. Perfluorinated greases such as Braycote 631 RP,

they exhibit excellent shelf life due to their inertness.

Additional Information

Temperature

December-54ºC to 204ºc (- 65ºF to 400ºf)

Limitations

Braycote 631 RP is only slightly soluble or insoluble in most fuels and oxidizers available in propellant service, and in most cases.

materials other than organic solvents and fluorinated solvents. Compatible at Normal operating temperatures

traditional metals, plastics and elastomers. Braycote 631 RP may be negatively affected by Lewis acids, e.g.

aluminum chloride at high temperatures. Newly exposed friction surfaces of aluminum, magnesium or titanium

alloys can react with Braycote 631 RP under certain conditions. Such systems should be thoroughly evaluated. Surface

it should be well cleaned from organic rust inhibitors before applying grease to ensure proper lubrication. This product is not

recommended for use in applications under vacuum and at loads exceeding 100,000 psi for a long time.

Packaging

Braycote 631RP is packaged in 2 oz (AVDP) disposable syringes, 1 lb plastic containers, 1.75 lb cartridge and 45 lb bucket.
