Usa Sealing Vacuum Fitting Straight Reducer 1 in x 3/4 in Stainless Steel 304

SKU CH-WQHQ-TVAHA

Straight reducer joins 1 in and 3/4 in vacuum tubes, stainless steel 304 rated to 10-7 torr at 72 Degrees F

  • Reduces tube size from 1 in to 3/4 in for flexible vacuum routing
  • Stainless steel 304 construction resists corrosion in demanding environments
  • Straight adapter shape simplifies inline installation without angular offsets
  • Vacuum rated to 10-7 torr at 72 °F for high-vacuum reliability
  • Withstands temperatures up to 320 °F for elevated-heat applications

Straight Reducer Vacuum Fitting

This straight reducer connects a one-inch tube to a three-quarter-inch tube in vacuum systems. It is manufactured from stainless steel grade 304 for corrosion resistance. The adapter carries a vacuum rating of 10-7 torr at 72 degrees Fahrenheit.

For Vacuum Line Transitions

Suits technicians adapting between different tube diameters on high-vacuum lines. Not intended for pressurised hydraulic or pneumatic circuits. Builders needing a flanged connection with bolt holes should select a different fitting style.

NW Flange Interface

Both ends use an NW connection type with a flange outside diameter of 1.563 inches and a flange thickness of one-eighth inch. Maximum operating temperature reaches 320 degrees Fahrenheit. Trade numbers 16 and 25 apply to this configuration.

Questions about this item

Should I pick the 1 in x 3/4 in size or the 16 and 25 trade numbers?

The 1 in x 3/4 in dimensions describe the actual tube outer diameters; trade numbers 16 and 25 are catalogue codes for the same fitting

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

It indicates the fitting can maintain a high vacuum down to 10-7 torr when measured at 72 Degrees F

How does the NW flange interface limit what I can connect?

The NW flange on both sides uses a 1.563 in outside diameter and 1/8 in thickness with no bolt holes, so it mates only with matching NW components
