prevent contaminants such as dirt, dust and moisture from entering the cylinder

Wipers

Overview

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.

Most common types of Wipers

Canned Wipers

Are straight cut rod wipers with a plastic or metal casing to help with corrosion. Good for heavy duty applications with excellent protection against heavily deposited dirt. They also decrease the friction between the wiper and the groove.

Snap-in Wipers

Snap-in wipers are for standard housings and provide excellent protection against contaminants such as dirt and mud. Its back support area prevents any swaying or bending of the seal. The straight cut lip geometry provides more force and a connected area between seal and rob to maximize wiper performance.

O-Ring energized Wipers

O-Ring energized PTFE wipers are good for dry-running applications. They have excellent thermal and chemical compatibility when used with an FFKM O-Ring. Its features include low friction, long seal life, and excellent thermal and chemical compatibility and protects the primary seal from contamination. Very good for high-speed reciprocating applications.

Quality You Can Rely On

Measurement

All parts are measured on our Zeiss O-Machine and or Keyence CMM, which utilize optical and contact measurement technology in a comprehensive analysis. The O-Machine includes multi-sensor coordinate measuring, white light sensors for non-contact assessments and extremely accurate 3D scanners.

We follow AQL 2.5 levels 1 and 2 sample size quantities, and all molded parts are manufactured to RMA A2 tolerances.

What comes with your orders:

Every order is sent with either a paper or digital QC document that includes ID, OD, C/S, Height, angles, and any other dimensions your organization feels critical.

Materials

Our rubber and plastic materials supply is diversified amongst the top compounders in North America. Each polymer has been qualified to meet typical exploration and production well conditions, including mechanical, tribological, thermal, and specific immersive properties.

What comes with your orders:

Every order comes with an MTR that includes a batch number, cure dates, and a set of mechanical properties.
