Vacuum pump flap valve material
Used as external source of vacuum for an OKI SA4 desolder station but not
necessarily OKI. Perhaps 20 to 30 years old. Simple 25W Japanese motor driving epicyclic rotary to reciprocatory bearing with linkage to a disc of rubber . Other side of the rubber a chamber with a Al closure plate with 2 holes and matching cover with a gasket between. This gasket has what was probably 2 simple flaps profiled from the disc which has disintegrated, seating over the hole/well combinations in Al disc and cover. The material now looks like , and has the structural integrity of , translucent orangey-brown gelatine sheet. At the moment I'm profiling a disc of silicon rubber, but if that does not work , anyone have any idea what the original material was? |

I suspect the original material was that translucent orange-brown formulation of latex they use for baby feeding bottle teats |

When was the last time that you were involved with baby bottles ? I don't think they've actually been that orange-y coloured stuff since we had our kids 30 years ago ! The ones that my daughters have now are all just semi- clear ... Arfa |
