Cylinders

Fully compatible with industry standards, Progressive’s Mold Cylinders offer features that deliver performance advantages at a competitive price and delivery.

• Black-Nitrided Graphitic Steel Glands: Competing products commonly use bronze glands, which are prone to fluid bypass and leakage under cyclic loading, but Pro’s glands are precision-machined from graphitic steel and treated with a Black Nitride surface treatment process. This increases surface hardness, improves wear resistance, and provides better sealing performance over the life of the cylinder.
• Re-Engineered Internals: Improved seals and increased contact surface area throughout the internal seals result in higher performance and a longer service life.
• Installer-Friendly Design: Six wrench flats on the rod — versus the two found on others’ products — allow for faster, easier installation with a standard wrench.
• Full Industry-Standard Compatibility: Unlike imported cylinders, Pro’s Mold Cylinders conform fully to NFPA industry standards — making them immediately familiar to designers, mold builders, and molders — while still delivering enhanced performance.
