⚙️ Key Features

• D4/D6 seawater-filter clamp
• Approximate catalogue weight: 0.28 kg
• Uniform V-band clamping
• Used with strainer 21368504 and O-ring 995147
• Designed for wet marine cooling-system service

🔌 Function

The clamp secures the seawater-filter cover or housing and compresses the sealing O-ring evenly.

⚠️ Common Signs of Failure

• Water leakage around the filter
• Clamp band cracking or distortion
• Damaged tightening bolt
• Cover movement
• Air entering the seawater pump suction

🛠️ Service Notes

• Bring the two flanges squarely together before the clamp goes on — a V-clamp centres and holds a joint but cannot pull a misaligned pipe into line
• Seat the clamp evenly round the flanges and nip it up lightly, then tap around the circumference with a soft mallet so the band settles and the flanges centre before final tightening
• Tighten in stages to the figure in the workshop manual for your engine and no further; the clamp is meant to pinch the flanges while still allowing for expansion and vibration, and overtightening distorts the band or the flanges
• Renew the clamp if the band is stretched, cracked or corroded, or if the bolt, nut or trunnion is damaged — a fatigued clamp can let the joint go completely
• Recheck the clamp after the first run up to working temperature, and again at the next service
