Question Spectra watermaker o rings

I am replacing the membrane on my Spectra Ventura 150 watermaker after ~ 6 years of use. I believe it would be prudent to replace the O rings on the ends of the membrane housing. I priced them from the local Spectra dealer and they want $29.00 plus tax and shipping for these 6 o rings. They appear to be 4mm x 58mm for the 2 big ones and 3mm x 19mm for the 4 smaller ones.

I can get o rings from my local industrial supply house for a fraction of the Spectra cost. Can anyone help me as to the material and hardness specs for these o rings. Buna-n, soft Buna-N, silicone, EPDM, Viton, etc.

I would think Buna or Viton would be Ok. Viton is a little tougher and more heat resistant, not an issue in your application. Silicon normally used for applications where the equipment may get quite hot.

Is there anything wrong with them?
If not, why replace them with possible risk of the wrong ones?

Re: Spectra watermaker o rings

Replace them only if you see cracks in them,
Otherwise,apply some silicone grease,and that's it
