The most economical of the sealant fitting family is the standard giant buttonhead fitting. It features a one-piece body design, conventional cage crimp and is ideal for small diameter ball valves in conventional oil service. Rubber caps are available to protect the buttonhead flange from damage due to exposure and corrosion.

Larger sizes come with a double-ball check, the smallest size has a single-ball check.

* Not suitable for injecting heavy sealants at high pressures.
