I., writes:Why do air-brake hose freeze in cold weather? On a real cold morning I canhardly bend the hose enough to coupleor uncouple; on a warm or rainy day thehose are as limber as a rubber band. Whyis this? A.—The ducking or canvas inthe hose, unless well covered at the endsand all over the surface with a good coatof rubber, will absorb moisture in dampand rainy weather and freeze hard whenthe weather turns cold. Moisture is morereadily taken up by hose whose outer rub-ber surface is checked and cracked. Theseare the hose you will find freeze stiffer.•\gain, rubber naturally stiffens with cold.
