Suction toy repair

Hello,

   This installment is for those small clear suction toys you buy from the adult toy shop, e-bay, and from dealers in Hong Kong. They work well, they are a clear plastic cup of varying sizes that has a plastic screw drive that pulls back a plastic plate with usually two black rubber o-rings. First off the O-rings are usually the basic black rubber o-rings, not silicone, nitrile, or epdm. To this be sure you only use Teflon or silicone or a combination of the two for greasing them, any mineral oil or Vaseline will ruin them! If you have damaged the o-rings in some way, fear not you can replace them! Try to use the following if you can for o-rings for more durability and longer life;

• NITRILE RUBBER (better)
• HBNR (best)
• EPDM (good)
• standard rubber (ok)

Using Nitrile, HBNR or EPDM you can use any lubircant you wish, mineral oil, vaseline, or silicone/Teflon lubricants.

     You'll need different o-rings for different size suction units. the easiest way is to go to an autoparts store and get a seal pick tool, this looks very similar to a dental pick, it's sharp on the end, and smooth down the shaft so as to not cut or damage the o-ring. Once you have the o-ring removed, take them into the auto parts store and have them see if they have the same size, it'll be metric in it's size since these are made in China. Try to see if you can get something better than the standard black rubber, if they can tell the size, then see if you can order HBNR fro the most durability. Always lubricate the rings after you install them before you screw the plate back into the cup.

     If your suction toy arrives with a chip in the base where it contacts skin, this will be a problem. This will cause both a lose of suction when using, and can be very uncomfortable. The way to repair these is to repair it with durable epoxy, here is a list of what you will need;

• JB Weld epoxy (2 part)
• 90% rubbing alcohol
• 1500 grit sandpaper (auto parts stores)
• wax paper
• flat smooth block of wood
• thumb tacks

Clean the damaged areas of the vacuum cup with a clean rag and 90% alcohol several times to remove any grease or oil. Then mix an even amount of PART A and PART B of the epoxy together and blend with a toothpick until it's ones even steel gray color. use the toothpick to apply the mixed epoxy to the chipped area then use a clean toothpick  smooth the area off level with the rest of the suction surface.  Now place the cup onto the wax paper on a smooth flat surface over night. The next day you can peel away the wax paper, clean with rubbing alcohal, if the surface isn't smooth enough use thumb tacks to attach the 1500 grit sandpaper to a smooth block of wood, and place the suction surface down onto the paper, and gently slide it around in a circular motion ont he flat surface a few times, then check to see if it's smooth.
