GASKET TYPE : The S and X cells share the Flow Field gaskets and are produced with either 2.5 cm x 2.5 cm and 5 cm x 5 cm active area – see photo below
SINGLE GASKETS & PACKS OF GASKETS (A, S and X cell): Gasket can be ordered individually, however, we also offer packs of Spacer/Cover gaskets with a volume discount. These pack includes gaskets with thicknesses that will allow testing and compression of almost any electrodes thicknesses. Typically the PTFE Thin Pack will be combined with one of the PTFE, VITON or EPDM Thick Packs.
PTFE Thick Pack includes sets (one pair) of
- 1 set – 0.5 mm PTFE
- 1 set – 1.0 mm PTFE
- 1 set – 2.0 mm PTFE
VITON Thick Pack includes sets (one pair) of
- 1 set – 0.5 mm VITON
- 1 set – 1 mm VITON
- 1 set – 2.0 mm VITON
EPDM Thick Pack includes sets (one pair) of
- 1 set – 0.5 mm EPDM
- 1 set – 1 mm EPDM
- 1 set – 2.0 mm EPDM
GENERAL: Gaskets are supplied in either PTFE, VITON or EPDM. VITON and EPDM is more flexible and will easily seal the cells, however, the minimum thickness of VITON/EPDM gaskets is 0.5 mm. PTFE gaskets are more rigid but comes in thicknesses down to 0.05 mm. Combination of several (both PTFE and Viton) gaskets can be done to ensure right electrode thickness/compression.
PTFE: Overall most corrosion resistant material and comes with thicknesses down to 0.05 mm. But rigid and less good sealing properties
VITON: Compressible that will make cell sealing easy. Redox-Flow recommends VITON (and PTFE) for Vanadium flow battery applications – please see a chemical compatibility chart of VITON for your specific application
EPDM:Compressible that will make cell sealing easy. Redox-Flow recommends EPDM (and PTFE) for alkaline conditions – please see a chemical compatibility chart of EPDM for your specific application
