When you specify a rubber or silicone part, one number drives almost everything downstream: Shore A hardness. It tells a buyer, engineer, and molder how stiff the part will feel, how much it will compress, and how it will behave under pressure and temperature. This guide explains what Shore A measures, the ranges used for […]

Need to filter sizes fast? Use the interactive AS568 O-ring size chart tool — search any dash number and toggle between inches and millimeters, or embed it on your own engineering resources page. The AS568 O-ring size chart is the reference every buyer, engineer, and maintenance planner reaches for when specifying inch-series O-rings. Published by […]

Many engineers assume that ordering custom rubber parts means committing to tens of thousands of pieces and a five-figure tooling bill. That assumption stops good prototypes and low-volume production runs before they start. In reality, most custom rubber and silicone components can be produced in small batches—sometimes a few hundred pieces—using the right process and […]

FKM (Viton) Temperature Range & Limits FKM (Viton®) is the go-to fluoroelastomer for chemical and heat resistance, but its temperature window is not a single number—it depends on grade, cure system, and whether the limit is continuous or intermittent. This guide explains the real FKM temperature range and what degrades it, with links to our […]

HNBR & FFKM Elastomers: When Standard Rubber Isn’t Enough When NBR or FKM starts failing—under sour gas, high dynamic load, or the most aggressive chemicals—engineers step up to HNBR and FFKM. These specialty elastomers extend service limits dramatically, but at a cost that must be justified. This guide explains when to specify them, how they […]

Appliance Rubber Seals for White Goods Washing machines, dishwashers, refrigerators, ovens, and water heaters rely on appliance rubber seals to contain water, steam, and heat for a decade of daily cycles. The wrong compound leaks, odors, or cracks prematurely. This guide covers the materials and designs used in white goods, with links to our silicone […]
