Ribbed Square Tube Reducer Sleeve Stepped Design Plastic Reducer Sleeve Hollow Square Tube Insert

Product Type: This connector part is a hollow square tube reducer sleeve designed to convert a 50 mm square tube to a 38 mm square tube with a exact insert fit.

Function: As a tube reducer, it helps bridge different square tube sizes so connected sections can be matched, joined, or adapted more neatly.

Construction: Made as a plastic reducer sleeve with a ribbed, stepped exterior, a square open end, and a notched opening on the other side for a defined shape.

Key Advantage: The square tube adapter sleeve offers a simple way to adapt tubing without bulky hardware, while the black finish and compact 21 g weight maintain-it unobtrusive.

Purpose: Sized with visible millimeter measurements, it is intended for practical tube conversion where a snug square tube insert is needed for clean alignment and support.
