For Sale is ONE Hydraulic Pump Valve Seal for most Antique Barber Chairs. 

This part is only the seal that replaces the original rubber in the base pump, brass part is not included. 
Some chairs require ONE or TWO seals within the inner plunger and outer cylinder. If you are replacing the part yourself, please check prior to ordering the part to match the fitment. 
Part is oil resistant and lasts longer than the original rubber part that came with the chair. 
This seal fits most Koken, Theo A. Kochs and Emil J. Paidar hydraulic pump bases. It is threaded to just simply screw off the old part and screw on the new part.
This does not replace metal valves in the base.
If your chair slowly lowers down after pumping up and does not stay up, this most likely will fix the problem for you.
We also offer the service to rebuild and fix the bases if you would like. Send us a message with any inquiries.
