JHWFJ-30 - Williams - 16" to 48" Flange Jack

The Williams JHWFJ‑30 Flange Jack Set is a heavy‑duty, professional solution for safe, controlled separation of pipe flanges during maintenance, repair, and gasket replacement. Designed for pipeline, refinery, utility, and industrial plant environments, these flange jacks provide smooth, even separation without damaging flange faces.

The JHWFJ‑30 is sold as a matched pair, allowing technicians to apply balanced force on both sides of the flange. This controlled approach prevents distortion, speeds up gasket removal, and significantly improves jobsite safety by eliminating hammering, flying wedges, and sparks.

With a flange diameter capacity from 16" to 48" (125 lb cast iron), the JHWFJ‑30 is ideal for large‑diameter piping systems. Its robust construction and compact working profile make it suitable for confined or hard‑to‑reach locations, where traditional separation methods are unsafe or impractical.

Manufactured in the USA to professional standards, the Williams JHWFJ‑30 delivers reliable, repeatable performance for technicians who require a safer and more efficient method for flange separation.

Ideal for: Pipeline maintenance, refineries, utilities, HVAC piping, water & wastewater facilities, and industrial plant shutdown work
