Highland Delrin DIN Regulator Cap (Part # HL401)
By Highland (XS Scuba) | Technical First Stage Protection | Authorized Dealer
Protect the precision threads and critical O-ring seal of your first stage with the Highland Delrin DIN Regulator Cap (HL401). Precision-machined from solid Delrin polymer, this heavy-duty threaded dust cap seals completely over 200-bar and 300-bar DIN connections. Unlike cheap press-fit plastic plugs, the HL401 threads securely in place to block moisture, salt spray, sand, and impact damage during gear washing, storage, and transport.
Key Features & Technical Benefits

- Knurled Grip Surface: Diamond-knurled outer collar allows easy hand-tightening and removal even with cold hands or thick drysuit gloves.
- Included Nylon Cord Lanyard: Features a durable cord lanyard to loop around your first stage body so your cap is never misplaced on boat decks.
