No More Lost Caps or Leaking Hatches — Built for the Harshest Marine Conditions

A missing deck fill cap or a cracked, ill-fitting hatch cover is more than an inconvenience — it's a contamination risk and a safety hazard. This PUM + Nylon marine deck fill cap fits a standard 50mm cutout and connects to a 38mm inner diameter hose, making it compatible with the vast majority of existing boat and RV installations. The stainless steel retaining chain keeps the cap secured to the fitting at all times, so it can never be lost or misplaced. Available in White and Black, with Blue caps for water hatches and Red caps for fuel hatches — a clear, industry-standard color coding system that prevents dangerous mix-ups.
