Henleys Easiflow Stern Tube

Easiflow Stern Tube

The Easiflow Driveline system takes the place of the conventional stern tube, intermediate housings and the inboard flanged bearings. Easiflow is a one design system to suit all types of vessels whether they are constructed in GRP composite, timber, aluminium, steel or ferro. Easiflow is constructed from a Hi-tech woven unidirectional fabric which is pre-impregnated with a thermo setting Epoxy resin, then laminated and cured under pressure using the latest techniques to ensure optimum density and stability.

The Easiflow stern tube system is certified by SGS M&I Safety Inspection Services Ltd. Over 80% of all vessels constructed in New Zealand use this unique system.

Easiflow can be installed using orca chok resin or traditional epoxy and glass fibre for timber and GRP or EasiChok or chockfast resin for steel, aluminium and ferro construction. Easiflow can be fitted with the Kiwi Shaft Seal, PSS, Deep Sea, Duramax or Strong seal, all of which are dry gland forced cooled seals. The drive tube can also be fitted with a combination of bearings, singular or outboard and inboard. The bearings mostly used are Thordon Compac, Thordon XL and Duramax, although any other specified type can be used as the I.D. of the tubes have been selected according to world wide bearing specifications.

The installation of the Easiflow System is extremely simple.

For timber and glass vessels, line bore to give a clearance on the tube and epoxy into place.
For steel and aluminium vessels, a tube is welded into place giving a clearance of approximately 4mm around the diameter of the easiflow tube. Float the tube within the welded tube, for correct alignment, then pour an easichok, our brand of fitting resin, to set in place.

Full installation instructions are supplied with all products. The Easiflow driveline system has been installed in Lloyd's and M&I surveyed vessels and caters for shafts from 3/4" to 4" in diameter.
