[Stamp] RECEIVED 27 AUG 1936 Messrs. Rolls-Royce Ltd., Derby. Dear Sirs, Confirming the interview our Managing Director, Mr. Mountain S. Angus, and the Writer had with your Messrs. Mills, Bailey, and Day at your Works on Monday last, we very much appreciate the opportunity of discussing our Angus Oil Seals, "Gaco" Oil Resisting Mouldings, and Rubberised Chrome Leather Protectors. We were glad to learn that you found these products interesting for various applications on your design. As we explained, the leather used for the sealing element of our Oil Seals is specially selected, tanned and processed for this purpose, and formed to a high degree of accuracy; this results in exceptionally good sealing and wearing properties. For applications where the temperature reaches or exceeds 110°C. or 45 ft/p/sec. we supply our Oil Seals fitted with the sealing element made from "Gaco", which will be found satisfactory up to 170°C. and speeds up to 90 ft/p/sec. Our "Gaco", which is proofed against lubricants and fuels, can be very accurately moulded into almost any shape. Although not containing rubber, it has all the desirable properties of rubber; it is elastic, dense, and non-porous, and exceptionally resistant to ageing. The high surface finish and great resistance to abrasion make it ideal for oil sealing applications, and the friction on shafts or cylinders is only one fifth as compared with leather. continued. | ||
