Before you buy:

• The sizes are metric, with 2 / 2.5 / 3 / 4 mm cross-sections. They are not ISO 3601 sizes (cross-sections 1.80 · 2.65 · 3.55 · 5.30 · 7.00 mm) or inch AS568 sizes. You'll find those individually in the catalogue.
• NBR is not suitable for glycol-based brake fluids (DOT 3, DOT 4), ester oils, aromatic hydrocarbons or ozone. For brake fluid, water and steam choose EPDM from the catalogue; for hot oil and aggressive chemicals, FKM.
