Imperial offers a full service station to pressure test and inspect suits. Suits must be in serviceable condition at all times. The pressure test can reveal leaks that can not be seen with the naked eye. A well maintained suit increases your chance of survival, lasts longer, and saves you time and money. An experienced service technician can find seemingly minor defects that can cause major problems. Call (206) 783-5512 or 1-800-592-6255 to find out who your local Imperial Service Station is. The High Rider Ring is made of neoprene and attached by zippers making it easy for you to replace yourself. Most other suits have air bladders (high rider rings) that must be brought into a certified station to be replaced.
Great Care is taken during the manufacturing process and each suit is pressure tested upon completion. The Imperial Immersion Suit has the longest history in the U.S. The founders of Imperial International, Inc. have been in the marine industry for decades, and care very much about the individuals who work in it.
