Description

Tillotson 206NP 1.125" Flange Gasket – .020" Thick with Pulse Hole


The 206NP Tillotson Flange Gasket is designed to create a reliable, airtight seal between your carburetor and intake manifold. Featuring a 1.125" bore, .020" thickness, and a precisely cut .125" pulse hole, this gasket is compatible with Tillotson HL-380A, HL-380B, and all EC X380-series carburetors.


This high-quality paper gasket includes a dedicated pulse hole to align with both your carburetor and intake manifold—critical for proper fuel pump function and carburetor performance.


Key Features:

  • 1.125" bore diameter – matches HL-380 and X380 series
  • .020" thickness – ideal for tight, consistent sealing
  • .125" pulse hole – ensures proper operation of internal fuel pump
  • Designed for gas and methanol racing applications
  • Easy-to-trim paper gasket construction


Installation Notes:

  • Do not install without punching out the pulse hole. The pulse must align with both the carburetor and the intake manifold.
  • If your intake uses a notch instead of a round pulse hole, fuel exposure may cause gasket deterioration, potentially blocking the pulse channel and disrupting carburetor performance.
  • For best results, we recommend using only EC-built intakes, which are precision-matched for these gaskets.


Specifications:

  • Bore Diameter: 1.125"
  • Gasket Thickness: .020"
  • Pulse Hole Diameter: .125"
  • Material: Treated high-performance paper


Ensure a proper seal and consistent carburetor performance with the 206NP Tillotson Flange Gasket – precision-fit for HL-380 and EC X380 carburetors.

FAQ

Q1: What carburetors does the 206NP flange gasket fit?

A: This gasket is designed for Tillotson HL-380A, HL-380B, and all EC X380 series carburetors with a 1.125" bore intake flange.


Q2: Does the pulse hole need to be punched out before installation?

A: Yes. The .125" pulse hole must be punched out to align with your carburetor and intake. Failure to do so can cause fuel pump malfunction and poor performance.


Q3: Why does intake design matter when using this gasket?

A: Intakes with a notched pulse port (instead of a round one) can allow fuel exposure to degrade the gasket, possibly blocking the pulse channel. We recommend using EC-built intakes for best performance and reliability.


Q4: What’s the purpose of the thicker .020" gasket?

A: The .020" thickness provides a secure seal without excessively altering port height or spacing. It's commonly used in race kart and performance engine setups.


Q5: Can I use this gasket for both gas and methanol engines?

A: Yes, the 206NP gasket is compatible with both gas and methanol applications, assuming proper carb and intake fitment.
