Product Details

The Foster B3DC-BLUE is a 3/8" ISO-B dust cap in rubber for FHK / ISO 7241-1 Series B hydraulic quick couplings. It protects coupler (female half) from dirt, moisture, and damage when the coupling is disconnected, keeping the critical mating surfaces clean so the coupling stays serviceable. Colour: Blue.

Specifications

Why this accessory

• Keeps couplings serviceable — shields the precision mating surfaces from contamination that would otherwise foul the coupling.
• Sized to the coupling — the dust cap/plug body size must match the socket or plug it protects. This one fits 3/8" ISO-B (FHK) halves.
• Rubber construction — durable protection for storage and transport.
