The Seiken Hydraulic Brake & Clutch Parts Catalogue is a well-organized resource, especially for workshops and spare parts dealers focusing on Japanese, Korean, and European commercial vehicles.

The catalogue specifies fluid compatibility. Most Seiken rubber components (cups and seals) are designed for (glycol-based fluids). Unless the catalogue entry explicitly says "Silicone compatible," avoid DOT 5 (purple silicone), as it can swell standard EPDM rubber.

Each part is accompanied by a line drawing showing critical measurements: center-to-center mounting bolt distance, inlet port thread size (e.g., 10mm x 1.0, 3/8-24 UNF), and bore depth.

Ideal for independent hydraulic specialists and fleet maintenance teams . Not a generalist catalogue, but for pure brake/clutch hydraulics, Seiken delivers reliable, precise data.
