Tunstall Corp. produces a complete line of thermostatic radiator steam traps with ratings from 25” HG vacuum to 25 psig. All units are “normally open” to expel air and water and will “close” at saturated steam temperature thereby preventing steam from entering into condensate return lines. Each Tunstall steam trap features the Tunstall Capsule which has become the best steam trap replacement element available today.
