Product details

Stuffy Box with hose connection - Further development of the popular rubber Stuffy Box
On the vulcanized hose connection (3/8"), a tube is inserted and fixed with a clamp. The tube 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.
In addition, the bushing should be lubricated with the special grease at least once a year. To do this, remove the blind screw connection, lubricate the bushing and then close it again.

For lubrication, stuffy grease must also be purchased!
Note: 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).
