Materials

Our vacuum cups are manufactured from two materials:

PVC vinyl: This is our primary material as we find it to be the softest yet hardest wearing material - the soft, pliable nature of the product offers excellent sealing capacity with wear resistance which is greater than rubber.
Silicone: This material is also soft but provides a greater temperature range (see chart below). However it does not have the same wear resistant properties of vinyl. Although we carry some silicone cups in stock most are available on a special order basis
