  • Rated to 10-7 torr at 72°F for high-vacuum integrity
  • Withstands 320°F continuous operating temperature for thermal stability

Vacuum Fitting Straight Reducer

The USA INDUSTRIALS ZUSA-TF-VAC-29 is a straight adapter that connects a 1-1/2 in tube to a 1 in tube. It is built from stainless steel grade 304 for corrosion resistance in vacuum environments. The fitting carries a vacuum rating of 10-7 torr at 72 degrees F.

Verify Tube Sides and Temperature

Confirm that your system uses NW connections on both sides with the matching outer diameters of 1-1/2 in and 1 in. The maximum operating temperature is 320 degrees F, so ensure process heat stays below this limit. The flange outside diameter is 2.156 in with a thickness of 1/8 in and zero bolt holes.

Integrates Into NW Vacuum Lines

This straight reducer joins two NW flanges of different sizes without adding length or angles to the line. It requires compatible NW clamps and centring rings for sealing at each end. The design frees up space compared to stepped hose assemblies and suits high-vacuum applications rated to 10-7 torr.

Questions about this item

Does the USA INDUSTRIALS ZUSA-TF-VAC-29 include gaskets or clamps, or must they be purchased separately?

The fitting is supplied as a single stainless steel 304 straight reducer with NW flanges on both ends; gaskets and clamps are not included and must be sourced separately.

Should I choose this 1-1/2 inch to 1 inch reducer or a different size for my vacuum line?

Select this model when you need to step down from a 1-1/2 inch tube to a 1 inch tube while keeping NW flange compatibility; other Trade No. 25 or 40 sizes cover different diameter combinations.

What does the 10-7 torr vacuum rating mean once the fitting is installed in my system?

At 72 degrees F the joint will maintain a vacuum level of 10-7 torr, and the 304 stainless steel construction supports continuous operation up to 320 degrees F without degradation.
