Donaldson P226151 Flex Tube

This flexible stainless-steel tube has a 51 mm inside diameter and a 10 ft overall length. It is built for routing air or fluid in engine compartments where rigid piping cannot follow the required path. Mechanics and engine builders who need a durable, heat-resistant conduit for custom installations will find it suitable.

51 mm Inside Diameter

The single dimension that determines fit is the 51 mm internal bore. If the mating hose, clamp or port uses a different size the tube will not seal correctly and cannot be adapted without additional parts. Always verify the connecting component matches this exact bore before ordering.

Stainless Construction and Length

The 10 ft stainless length can be cut to the exact run needed, freeing the installer from stock fixed-length pipes. It requires compatible clamps or fittings at each end and enough clearance to accommodate the bend radius of the flexible wall. No additional coatings or liners are included.

Questions about this item

How does the 2 in (51 mm) inside diameter affect airflow in an engine system?

The 51 mm bore matches standard 2-inch intake and exhaust piping so air or exhaust flows without a restrictive step change at the joint.

What connection standard does the stainless flex tube use and what does it limit?

It slips over 2-inch OD pipe and seals with constant-tension clamps; the clamp style limits the maximum pressure the joint can hold.

What physical clearance does the 10 ft (3 m) stainless flex tube need for routing and mounting?

The 3 m length can be cut to fit; allow enough straight run on each end for two clamps and a gentle curve so the tube does not kink against brackets.
