Our O-Seal Fittings feature an o-ring set inside a precisely-machined groove, which squeezes against the mating part of a unit to create a leak-tight seal. We can customize these versatile devices to fit nearly any application, which makes it easy to quickly establish a leak-tight connection between threaded joints. 

• Mates with typical male and female NPT thread sizes between 1/8'' and 1''
