Overview:

FLOWTECH REAL-SEAL header and collector gaskets are a revolutionary break-through in exhaust sealing technology. Constructed of separate layers of "Dead Soft" aluminum, REAL SEALS provide a do-it-once solution that will not burn or blow out. REAL-SEAL gaskets will work when an o-ringed gasket will not because the "Dead Soft" aluminum conforms to create a leak-proof seal. REAL-SEALS can also be easily trimmed for port-matching and you can use them over and over again.

Features:

  • Suitable For Port-Matching
  • Will Not Burn Or Blow Out
  • Re-Useable
  • Water/Weather Resistant
  • Multi-Layer "Dead Soft" aluminum conforms to create a leak-proof seal
  • Made In USA
