Here are 2 new Viton O-Rings to fit the filter access door on your Rietschle VC- 700 rotary vane vacuum pump.     

Two 290 mm O-rings are required. This auction is for 2 O-rings. The photo caption indicates VC-300 since the 300 takes the same O-ring. 

Please note:  this may not always be in stock, so please allow 3 weeks lead time if not in stock.

Filter changes are recommended on a yearly basis or when your exhaust back pressure gauge is in the red. This O-Ring can be replaced when you change filters.  We also have the mesh door gasket in case you damage it when changing the filters.

E-mail me with any questions.   Thank you for taking the time to look at this item.  I also have some replacement vacuum pumps available.
