1 1/8" HB to 1 1/4" HB straight adapter

Product Description

Ensure watertight marine hose connections with our USA‑made marine composite hose barb coupling adapter. Engineered with high-strength composite, this durable adapter resists flexing, electrolysis, UV degradation, and harsh marine chemicals—making it the ideal choice for demanding boating environments.

Dual-barb sizing of 1‑1/8″ ID to 1‑1/4″ ID provides flexible splicing and hose size adaptation. The design supports double-clamp installation, delivering unmatched security—perfect for high-vibration or pressurized marine plumbing.

The hex-shaped center offers a reliable grip for tightening, streamlining installation even in tight quarters. At an overall length of 2.90″, this straight coupling ensures stable, compact connections.

Comparable in quality to industry-standard composite hose fittings used by trusted manufacturers (e.g., MarineEast and Gemlux), this adapter meets the high durability and corrosion standards expected by professional marine builders
