These steel springs are part of our 50% off Bug-Out Sale, until our overstock is exhausted, then they return to regular price.
Price is for one spring, 38mm wide and fits all models of solvent filters. These springs are made of high tensile carbon steel covered with a corrosion resistant coating. This means that they are durable under pressure, heat, and solvent. They will retain their compression strength, even when compressed over a long period of time inside your cannister. Tightly compact springs between (barrel) and cups for a coil of steel (headspace) that allows room for expansion & your cleaning brush, but hold cups tightly in place.
