Benefits of FKM (Viton®) Seals
FKM sealing O-rings provide excellent resistance to high temperatures, oils, cleaning chemicals and many industrial fluids. This makes them particularly suitable for hygienic manufacturing environments where aggressive cleaning agents and frequent sanitation procedures are common.
Combined with 316 stainless steel construction, FKM seals help maximize service life in demanding applications.
Frequently Asked Questions
What are metric push-to-connect fittings?
Metric push-to-connect fittings are pneumatic fittings designed specifically for metric outside diameter tubing such as 4mm, 6mm, 8mm, 10mm and 12mm tube sizes.
Can metric and inch pneumatic fittings be used interchangeably?
No. Metric and inch tubing have different outside diameters and should never be mixed. Always match the fitting to the tubing outside diameter.
Why use 316 stainless steel metric fittings?
316 stainless steel provides superior corrosion resistance and excellent durability in washdown, food processing, pharmaceutical and chemical environments.
What industries commonly use metric pneumatic fittings?
Metric fittings are commonly found on European machinery, robotics, automation equipment, packaging machinery, food processing systems and pharmaceutical production equipment.
What seal material is used in these fittings?
These fittings use FKM sealing O-rings, commonly known as Viton®, offering excellent chemical resistance and high-temperature performance.
Are these fittings suitable for food production facilities?
Yes. The 316 stainless steel construction and FKM seals make them well suited for food processing, beverage production and hygienic manufacturing environments.
Can these fittings withstand washdown procedures?
Yes. These fittings are designed to withstand exposure to water, cleaning chemicals and frequent sanitation procedures commonly found in food and pharmaceutical plants.
What metric tube sizes are available?
Common sizes include 4mm, 6mm, 8mm, 10mm, 12mm and 16mm tubing, depending on the fitting style and configuration.
What pressure can these stainless steel fittings handle?
Most models are rated to 290 PSI, while selected S-Series models offer working pressures up to 420 PSI.
What is the advantage of FKM over standard NBR seals?
FKM provides superior resistance to heat, oils, cleaning chemicals and many industrial fluids compared with standard NBR sealing materials.
