Your old brass valve is pitting, the handle's seizing up, and you're not about to strip the plumbing out of the bilge or the van's water line just to swap it. The TruDesign 1/2in BSP ball valve drops in on the same thread, and it doesn't corrode. Glass reinforced nylon composite means no electrolysis, no pitting, no slow leak six months from now. It shrugs off diesel, petrol and antifouling paint splashes. UV resistant, so the sun on the deck isn't going to crack it by summer. Works from -20°C to +80°C, which covers a frosty outback night or a hot engine bay. One quarter-turn, full flow. Done
