Description
The Nautos Low Friction Ring (30 mm & 40 mm) is a precision-engineered, lightweight alloy ring designed to minimise friction and wear in high-load marine rope and control line systems. The hard-anodised aluminium body with a Teflon® finish enables extremely smooth movement under load, making it ideal for boaters across Ireland dealing with challenging coastal conditions and tight control-line routing.
Available in two outer diameters (30 mm & 40 mm), these rings suit a variety of rope sizes and applications—whether you’re upgrading halyards, vang systems or high-performance control lines. Their compact size, robust build and proven performance make them especially suitable for Irish sailing, cruising and workboat environments where reliability, durability and low-maintenance are key.
Use cases range from dinghy rigs to larger cruising yachts where reducing friction directly improves handling, responsiveness and system longevity.
Features
- Available in 30 mm and 40 mm outer diameters, offering flexibility for different rope sizes and applications.
- Hard anodised aluminium construction with a Teflon® coated finish ensures ultra-low friction and high wear resistance.
- High safe-working loads and breaking loads (for example, the 40 mm version: SWL ~ 980 kg, breaking load ~ 1,800 kg).
- Suitable for high-strength control lines and halyard systems; supports rope diameter up to ~10 mm in the 40 mm version.
- Lightweight design helps reduce weight aloft—beneficial for yacht performance and handling.
- Ideal for retrofit installations and upgrades in Irish yachts and boats where components need to endure salt-spray, vibration and frequent use.
- Provides a clean, professional finish on the deck or rigging layout—important for owner-operators and commercial vessels alike.
