Product Description
Eccentric Reducer Overview

An ecc reducer is the same fitting buyers search for as an eccentric reducer, and the shorter form is what appears on most purchase orders and shipping marks. This 10 x 8 inch ecc reducer is formed from SS316L tube, beveled to B16.9, pickled and passivated, and it is installed with the flat side down so the horizontal run drains.

The distinction matters in practice. A concentric fitting would leave a pocket at the size change where gas collects on a pump suction, while this fitting keeps the bottom of the line straight. For lines carrying slurry or crystallising product, the flat side down arrangement also stops solids from settling in the transition.

Design, Inspection and Application Highlights
  • Search friendly naming: the ecc reducer is listed under the abbreviations used on purchase orders, so buyers do not have to translate between ecc and eccentric when checking availability.
  • Drainable installation: the flat bottom keeps the run level, preventing liquid traps on pump suction and gas pockets on discharge lines.
  • 316L weldability: low carbon content limits carbide precipitation, so the ecc reducer can be welded without a post weld heat treatment in most process lines.
  • Surface condition: pickled and passivated inside and out, with the heat tint removed before packing.
  • Application fit: pump suction headers, gravity drain lines, slurry transfer and tank outlet piping.
Frequently Asked Questions
Q: Is ecc reducer the same as an eccentric reducer?

A: Yes. Ecc is the standard abbreviation for eccentric, and the ecc reducer is dimensioned and installed exactly as an eccentric reducer. Only the purchase order wording differs.

Q: Which way up should the ecc reducer be installed?

A: Flat side down in horizontal liquid lines so the line drains and no gas pocket forms. On pump suction the flat side is also kept down to avoid air locking.

Q: Can this size be supplied as a concentric fitting instead?

A: Yes. The same 10 x 8 inch size is produced as a concentric reducer from the same material, and both types can be shipped in one lot if the line needs both.

Q: What is the wall thickness of the SCH40S ecc reducer?

A: 9.27 mm at the 10 inch end and 8.18 mm at the 8 inch end, measured on the finished fitting and reported with the dimensional sheet.

Q: Are stock sizes available for immediate shipment?

A: The 10 x 8 inch ecc reducer in SS316L SCH40S is normally held in stock and ships within 7 days, with pickling and certificate included.

Send the line size and the installation direction, and we will confirm whether the ecc reducer or the concentric version suits the run, with stock availability and price.
