    No, silicone grease is grease rather than oil. WD40 is best left in the shop.

    The original formula WD40 contains no silicone .
    WHAT DOES WD-40® MULTI-USE PRODUCT CONTAIN?
    While the ingredients in WD-40® Multi-Use Product are secret, we can tell you what it does NOT contain. WD-40® Multi-Use Product does not contain silicone, kerosene, water, graphite, or chlorofluorocarbons (CFCs).

    They do a silicone grease though https://www.wd40specialist.com/produ...one-lubricant/

    There is more than one type of silicone oil/grease, have a look at this link

    Just dont use it on metal to metal and if you do use it on plastic to metal make you use the right airgun oil and read the instructions

    All you need is the lightest smear of silicone grease on assembly. Just enough to make the o ring look shiny.

    I thought silicone oil on metal to metal issues was a myth

    HSE requires all chemicals likely to be used by workers nto have a COSHH risk assessment and they have to declare contents.
    They are white spirit 50% with mineral oil 15%, corrosion inhibitor 10%, wetting agent and perfume. 25% butane propellant

    Hi have a look at AQUA GEL silicone grease. Doesn't cause any problems with metal to metal contact. Seems to work very well. (for me).
    Cheers.

    Small pedant point:

    Silicon is a metal, widely used in semiconductors

    Silicone is a Silicon based polymer, some formulations of which can be used as lubricants.

    And as already pointed out WD40 has no silicone or silicon in it and is anyway a very poor lubricant.

    Silicon is not classed as a metal, it is a metalloid, it does not conduct electricity in all circumstances, it's a semiconductor and that's what makes it useful.

    Most O rings are nitrile and resist mineral oils and grease. Use whatever suits the assembly, eg moly grease for moving parts like pistons and loading bolts, silicone for static seals like gauges.

    Well probably yes but......"metalloid" is something of an oddball term since there is no agreed common set of characteristics which qualifies a metalloid and therefore the term is not useful in classification. Knowing that x is considered by some to be a metalloid is useless in determining what characteristics it actually has, and there is not even complete agreement on which elements are metalloids. Best interpretation is "similar in some respects to a metal". Not at all a useful classification.

    And in continued pedant mode - Silicon is useful not only because it is a semiconductor. It is a component of Silicone and its semiconductivity is irrelevant in this context.
