SEALING SURFACES

YOUR FINISHING PROCESS JUST GOT EASIER

Overview

Surface finish is vital in controlling the performance and life of the sealing surfaces in hydraulic and pneumatic components. Working at high pressures and with close tolerances, any slight surface imperfection will cause the system to leak, lose efficiency or fail prematurely. The right finish can be the difference in whether seals, gaskets and O-rings perform their job and is a critical part of system integrity in many different industries.

Sealing surfaces play a critical role in ensuring the performance of hydraulic and pneumatic components function properly across various industries. In manufacturing automation, pneumatic actuators and valves require clean, accurate sealing surfaces for reliable performance. In construction, agriculture and mining, heavy-duty equipment professionals rely on high performance seals and precision machined surfaces for long service life due to the harsh environments they are put under. In aerospace, due to the extreme pressures and temperatures hydraulic components are put under, surface finish directly impacting seal integrity and safety. Meanwhile, medical and food processing industries require pristine, contaminant-free surfaces to help ensure clean, sterile, leak-free operations where the cleanliness of the product and the reliability of the process is non-negotiable.

SEALING SURFACES MADE EASY-IN THE SHOP OR OUT IN THE FIELD 

FLEX-HONE® tools play a critical role in preparing proper sealing surfaces by producing a smooth, plateaued finish that enhances seal contact, reduces wear, and prevents leakage. Ideal for hydraulic and pneumatic components, the FLEX-HONE ensures consistent, high-quality finishes without compromising dimensional integrity.

FLEX-HONE® 

Key Benefits and Features of Proper Sealing Surface: 

  • Plateaued Surface Finish – Removes peaks while preserving valleys, improving seal engagement and reducing friction. 
  • Self-Aligning Design – Conforms to bore geometry for uniform finishing, even in out-of-round or tapered bores. 
  • Abrasive Action – Gently deburrs and blends surfaces without altering cylinder size or shape.
  • Improved Seal Life – Reduces wear and friction on seals, enhancing performance and extending service intervals. 
  • Versatile Application – Ideal for cylinders, valve bores, pump housings, and other critical sealing surfaces. 
  • System Efficiency: Proper seals mean that the pressure and flow control is consistent so that pumps, cylinders, actuators, and valves function effectively. 
  • Seal Longevity: A properly finished surfaces reduce wear and friction on seals, minimizing damage and extending maintenance intervals. 
  • Contamination Control: A superior sealing surface reduces the risk of contamination, which can damage internal components and degrade fluid quality.  
  • Safety and Reliability: Especially in high-pressure or safety-critical applications, a proper seal ensures that systems operate as intended, reducing the risk of failure, downtime, or hazardous leaks.
