TiAL F38 : 38mm Wastegate #16320

TiAL F38 : 38mm Wastegate
(4 reviews)  

The classic 2 bolt flange wastegate. We first produced the F38 back in 2001 and it's still going strong today. This wastegate has a 38mm valve - same as the MV-S, and its body is about an inch taller.

- 347 Stainless Steel Alloy is used for valve and valve housing.
- High temperature silicone Nomex reinforced actuator diaphragm.
- 17-7 PH Stainless Steel actuator spring gives consistent pressure at high
temperature, resists "relaxing" at temperature to 900F (483C).
- Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing the
same material used in the higher level gates for reliability and longevity.
- CNC Machined 304L 12mm thick weld flanges.
- Low Cost.
- Made is USA.
- Color anodized 6061-T651 aluminum actuator (Silver, Red, Blue, Purple, Black).
- Wastegates shipped with air fittings and stainless hardware.
- Flanges are an extra cost, they do not come with the wastegate unit.

Included with every Tial F38:

F38 Assembly
F38 Valve Seat
2 Gaskets
2 TiAL Air Fittings
2 Mounting Bolts
4 Flex Washers

Valve Stem Options

The TiAL F38 is the only wastegate with the option to choose the valve stem's
protective coating. To keep the overall cost of the unit down, the choice of
coating was left to the customer.
Lead Oxide which is present only when burning leaded fuels is corrosive to the
Black coating on the Street valve's stem. Extended use of leaded fuel will cause
performance problems and unreliable valve actuation.
The Silver coating on the Race valve stem is resistant to the corrosive effects
of Lead Oxide. Similarly works well with unleaded fuel. The Racing valve is
available for an additional charge.

*All 38mm wastegates now come with a
leaded safe racing valve.
