Stuffy Box EVOLUTION - further development of the well-established rubber Stuffy Box
On the vulcanized hose connection (3/8"), a tube is inserted and fixed with a clamp. The hose is passed over the water line and simply left open to the top. Existing air in shaft seal can easily escape and thus a permanent cooling / lubrication of the shaft seal is ensured. Via the second connection (comes as a standard with a dummy screw), optionally parts of the cooling water can be injected into the shaft seal. This is recommended for operation in tidal waters and "silt ports". The additional water provides additional rinsing and a significant increase in service time can thus be achieved.
The Stuffy Box Evolution shaft seal should be lubricated annually at least once with the included special grease.
: We recommend LOCTITE thread sealing
for sealing the tube tulle. The blind stopper for regreasing the gland should be equipped with a washer/o-ring (not included).
