⚠️ SIZE DETAILS — PLEASE READ ⚠️

This is a Nominal Pipe Size item and the dimensions of this item are based on the "Nominal Pipe Size" measurement system. The dimensions of this item differ significantly from those of Tube size material, which is sized by the true outside diameter of the material. Please refer to the dimensional detail table further down this page for the actual measurements of this item.

Description

A Smooth, Free-Flowing Way to Step Up or Down in Size!

The Ace Race Parts brand of Schedule 5 45° Weld Els are available in 321 Stainless! Our 321 Stainless Weld Els offer superior corrosion resistance in high temperature applications — especially applications that will see extended periods of wide open throttle (eg: a track car) or will see repeated high heat cycling (eg: a drag car that sees significant cooling between passes). With a slight addition of Titanium to stabilize the alloy at high temperatures, 321 Stainless is an excellent choice for turbo manifolds that will be exposed to high levels of heat over a prolonged period of time.

FEATURES

  • Schedule 5 (0.065"±) Wall Thickness
  • 321 Stainless Steel
  • Allows for a Smooth, Unobstructed Flow of Exhaust Gas
  • Durable Enough for a Wide Variety of Turbo Manifold Applications
  • Capable of Withstanding 1,600°F
  • Manufactured to ASTM A403/ASME B16.9 specifications

304 Stainless vs 321 Stainless

One major chemical difference between 304 and 321 Stainless is the addition of Titanium (Ti) in 321 stainless to help "stabilize" the alloy and to reduce the risk of corrosion in the heat-affected zone. When 304 Stainless is heated above 1,292°F for an extended period of time it may suffer from weld decay. Weld decay is reduced by the addition of titanium, making 321 Stainless ideal for use in turbo exhaust manifolds and other exhaust products that see high levels of heat over prolonged periods of time. Although 304 Stainless is more than suitable for most turbo manifold and other exhaust applications, 321 Stainless is the superior choice for heat-related corrosion resistance.

Ace Race Parts brand Pipe Size Reducers are available in nominal pipe sizes ranging from 1-1/4" to 3" and are available in popular alloys like 304 Stainless and 321 Stainless. A wide range of wall thickness options are available, including Schedule 5, Schedule 10, and Schedule 40. Stainless Weld Els can be paired with Stainless Steel Pipe and Stainless Steel Merge Collectors to create a variety of turbo manifold styles.

Dimension Disclaimer
Due to the allowed tolerances of pipe size material (spec: ASTM A403), all dimensions, including OD, ID, Wall Thickness, and Weight are approximate dimensions only. We make no guarantees that any of the dimensions provided for pipe or pipe fittings are exact measurements.
Notes
All ASTM A403 pipe fittings, except for Schedule 5 fittings, have a standard 37.5° bevel (±2.5°) on both ends. All straight lengths of pipe have a plain end with no bevel.
