Parker VA179-70 O-Rings Increase FKM Continuous High Temperature Limit by 20°C

October 04, 2018

 

Zatkoff's new high-performing, fluorocarbon (FKM) compound lineup features four incredible sealing products from Parker Hannifin that include VM100-75, VA179-70, VX065/VX165, and VM125. We are proud to carry such innovative elastomeric sealing solutions that provide long-term resilience in the face of demanding temperatures and a broad range of chemicals. One standout FKM compound is Parker's VA179-70 O-ring which is known for its exceptional performance qualities.

VA179-70 was added to our inventory due to its reputation as an industry-leading, high temperature fluorocarbon compound. In increasing the FKM continuous high temperature limits by another 20°C, VA179-70 fixes long-term compression set issues for customers using traditional FKMs, silicones or AFLAS® compounds.

VA-179-70 delivers a strong improvement in compression sets over traditional FKMs as evidenced by the low ratings illustrated in the graph shown here. The resulting recommended temperature range is -15°F to 437°F (-26°C to 225°C), and potential applications for VA179-70 O-rings include automotive, oil and gas, and industrial.
