Compensation sealing ring APS

precisionpistonrod

Overview
Designed with an Advanced Pitch Spring (APS) design, these spring-energized seals minimize friction in dynamic applications. They feature a polymer jacket energized by a slanted coil (advanced pitch spring) and are characterized by very small diameter and cross-section while providing compensation for hardware misalignment, eccentricity and seal wear.

Key features

• Advanced Pitch Spring (APS) design (slanted coil) energizing a polymer jacket
• Minimizes friction in dynamic applications
• Very small diameter and cross-section suitable for precision equipment
• Compensates for hardware misalignment, eccentricity and seal wear
• Precision fit for demanding instrumentation

Typical applications

• Microsurgical tools
• Life science seals (HPLC / UHPLC instrumentation)
• Surgical equipment and dental tools
• Precision reciprocating pumps and piston/rod sealing in analytical and medical instrumentation

Materials & options

• Polymer jacket (various engineered polymer options available)
• Metal spring: advanced pitch / slanted coil geometry
• May be manufactured to PFAS-Free* specifications depending on application and equipment requirements
• Available supporting resources: downloadable Spring-Energized Seals handbook(s) and an installation video (installation guidance for small-diameter seals)

Notes on PFAS
*PFAS-Free here means no intentional addition of PFAS materials to the product formulation but does not exclude the possibility of traces due to environmental prevalence of these substances.
