Description

16B-199 Tillotson Copper Inlet Seat Gasket – OEM Replacement for HL, HR, HM, HW, HB, HC, HX Carburetors


Premium Copper Seal | Protects Carb Body | Ensures Leak-Free Fit

The Tillotson 16B-199 Copper Inlet Seat Gasket is an OEM-quality copper gasket designed to seal the interface between the fuel inlet seat and the carburetor body. It helps prevent fuel leaks and protects the carburetor body from thread damage during seat installation or replacement.


Key Benefits:

  • OEM Copper Gasket: Precision fit for consistent sealing and durability
  • Protects Carburetor Threads: Reduces the risk of stripping the seat cavity
  • Leak-Free Performance: Forms a permanent groove during installation for reliable fuel sealing
  • Ideal for Rebuilds & Racing Use: A must-have for maintenance, especially on older or high-performance engines


Proper Installation Instructions (Highly Recommended):

To avoid fuel leaks and prevent thread damage to your carburetor body:

  1. Install the seat gently against the new copper gasket
  2. Slightly tighten the seat, then loosen it while keeping contact
  3. Repeat this "tighten-loosen-tighten" process 2–3 times
  4. This procedure allows the seat to form a groove in the gasket, ensuring a leak-proof seal

Never over-tighten. If you skip this process and overtighten, you risk stripping or cross-threading the carb body. Tillotson does not sell replacement carburetor bodies—meaning you'd need an entirely new carburetor.


Optional Tool:

If you're working on older Tillotson carburetors, you may need our Seat & Gasket Alignment Tool to ensure the inner diameters (I.D.) of the seat and gasket are perfectly concentric for optimal sealing.

FAQ

Q1: What does the 16B-199 Tillotson gasket do?
A: This copper gasket seals the fuel inlet seat to the carburetor body, preventing fuel leaks and protecting the threads in the carburetor seat cavity.


Q2: Why is proper installation of the 16B-199 gasket important?
A: Improper installation can lead to fuel leaks or stripped threads. Always follow the recommended tighten-loosen-tighten method to seat the gasket correctly and avoid damaging the carburetor body.


Q3: Can I reuse the copper gasket?
A: Reuse is not recommended. For the best seal and carburetor safety, replace the gasket every time you install a new inlet seat.


Q4: Does this gasket fit my carburetor?

Q5: What happens if I over-tighten the seat?
A: Over-tightening can pull or strip the threads from the carburetor body. This can render your carburetor useless, as Tillotson does not sell replacement carb bodies.


Q6: Do I need a special tool for installing this gasket?
A: While not required, we recommend using a gasket-seat alignment tool for older carburetors to ensure the gasket and seat holes are perfectly aligned.
