PITTSBURGH—Wallace Instruments is helping to take the guesswork out of seal testing.
The Surry, England-based company introduced its WAC11 Mk5 testing equipment, designed to more accurately measure compression stress relaxation characteristics of rubber seals, O-rings and gaskets.
CSR testing, Wallace said, is becoming a standard for durability specifications for a range of elastomeric parts in the automotive, aerospace and construction industries. Understanding the ability of a seal to hold its properties under compression and in a variety of environmental conditions is key to knowing the overall durability of the product.
"We pride ourselves on the accuracy, repeatability and productivity of all our equipment and our engineers, who really understand the science of testing, are continuously innovating to support our thousands of customers in managing the cost of quality and new product development," Chris Mundy, sales and service manager at Wallace Instruments, said in a news release.
The WAC11 Mk5 is "generational leap" over the company's Mk4 instrument, according to Mundy, who noted that the newer model is more accurate, affordable and easy-to-use. Additionally the Mk5, which is compatible with Windows-based software, allows for customizable compression testing.
"We offer a full range of jigs for standard and bespoke applications and the WAC11 Mk5 is backward compatible, so it can be adapted to take customers' existing jigs and fixtures for testing and we can refurbish and certify old jigs," Mundy said.
For more than 70 years, Wallace Instruments has offered materials testing equipment, specializing in products that measure physical properties—hardness, plasticity viscosity, cure and compression—as well as other characteristics.
