Highland Stainless Steel DIN Plug
By Highland by XS Scuba | SKU: HL402 | 316 Marine-Grade Stainless Steel | Factory Oxygen Clean
Protect your cylinder valves from costly thread damage and unexpected gas loss with the Highland Stainless Steel DIN Plug (HL402). Precision machined by XS Scuba from heavy-duty 316 marine-grade stainless steel, this solid threaded plug screws directly into 200 bar and 300 bar DIN tank valves to seal out water, salt, sand, and road grime.
Available at International Diving Centre—Vancouver's trusted technical dive retail hub—this plug acts as a critical safety barrier during transit, preventing your cylinder valve from slowly venting precious breathing gas if bumped open inside your vehicle or gear bag.
Accidental Leak Protection & Oxygen Cleaned
Equipped with a high-grade Viton O-ring, the HL402 creates a complete pressure-tight seal inside the valve opening. If your tank handwheel gets accidentally jostled to the open position during transport, the sealed plug holds full cylinder pressure—ensuring you never arrive at the dive site with an empty tank.
