Bulkhead and Bolted Fittings

      Bulkhead and Bolted Fittings

      Bulkhead Fittings are also known as tank adapters or compression fittings. Standard Bulkheads are spin-tightened, screwing together to create a seal against the tank wall. Bolted Bulkheads create this same seal through the tightening of nuts and bolts. Bulkhead Fittings can be made of various materials and can be used on all plastic tanks in most locations.

      See tabs above to learn more about Fitting Materials and Gasket Materials.

      Fittings Materials

      Polyvinyl Chloride (PVC) bulkhead fittings can be used in a wide variety of applications. It has excellent chemical resistance to most solutions of acids, alkalis, salts, and other organic compounds miscible with water. PVC is not resistant to aromatic and chlorinated hydrocarbons. (32˚F to 140˚F)

      Chlorinated Polyvinyl Chloride (CPVC) can be used in the same applications as PVC but can withstand higher temperatures. (32˚F to 195˚F)

      Polypropylene (PPL) is the lightest of the plastic bulkhead material and can be used in a wider variety of applications than PVC. (-4˚F to 195˚F)

      316 SST
      316 Stainless Steel is the strongest of all bulkhead fitting types. 316 SST has a very wide range of chemical resistance and can handle temperatures way beyond that of plastic fittings.

      Gasket Materials

      Ethylene Propylene DieneTerpolymer (EPDM) gaskets are designed especially for acids and can handle many aggressive chemicals, alcohols and environments over time. (-4˚F to 195˚F) Also called EPT or EPR.

      Viton, or FKM Fluorocarbon Rubbers, are the most chemically resistant, balanced, and have excellent overall properties. Viton is not suitable for caustic chemicals. (-20˚F to 302˚F)

      Cross-Link Polyethylene Foam gaskets have a wide range of chemical resistance that match our tank. X-Link has no form memory so removing this fitting after it has been compressed can cause leaks when re-installed later. (32˚F to 140˚F) Also called XLPE.

      Tealon is resistant to most chemicals, insoluble, inert, non-flammable, dielectric, naturally lubricated and thermally stable. (-40˚F to 302˚F)

      All dimensions and weights are approximate to the best of our knowledge. If exact size tolerances are required please contact our customer service department prior to ordering.
      Notice: Prices listed are FOB point of manufacture. A handling fee of $35 will be added to drop ship orders less than $1,500.
      Tanks shipped or will called from Corona will have a nominal freight-in surcharge added to price.
