JHWFJ-20 - Williams - FJ-20 2" to 20" Flange Jacks

The Williams JHWFJ‑20 Flange Jack Set is a professional‑grade solution for safe, controlled separation of pipe flanges during maintenance, repair, and gasket replacement. Designed for pipeline, industrial plant, and mechanical service applications, these flange jacks provide smooth, even flange separation without damaging flange faces.

The FJ‑20 flange jacks are sold as a matched pair, allowing technicians to apply balanced force on both sides of the flange. This eliminates uneven separation and reduces the risk of flange distortion. By replacing hammer‑driven wedges, the tool greatly improves jobsite safety by eliminating flying wedges, sparks, and impact hazards.

With a flange diameter capacity from 2" to 20", the JHWFJ‑20 is ideal for smaller and medium‑diameter piping systems commonly found in refineries, utilities, HVAC piping, and industrial facilities. Its compact design allows use in confined and hard‑to‑reach locations, making it especially useful for tight installations and retrofit work.

Manufactured in the USA to professional standards, the Williams JHWFJ‑20 delivers dependable, repeatable performance for technicians who need a safe and efficient method for flange separation and gasket removal.

Ideal for: Pipeline maintenance, industrial plants, utilities, HVAC piping, and general flange service work.
