Polyvent Tank Lid

POLYVENT HEAVY DUTY TANK LIDS

The quick and easy way to inspect, clean and fill water and fuel tanks. Polyvent is a heavy duty watertight tank lid which has these advantages over conventional lids:

• It is completely transparent. To find out if the tank needs filling or cleaning, all you have to do is look through the lid.
• It unscrews. So when the tank needs filling or cleaning, you can take the lid off in a few seconds and replace it just as quickly when the job is done.
• Tanks fitted with Polyvent lids are easily topped-up with a hosepipe or can. No dock pipes or vents are needed.
