1-1/2" Rebolt Hose Clamp – 37–43 mm – For Camlock Barb Fittings

RKTB-150 – 1-1/2" Rebolt Hose Clamp (37–43 mm) for Camlock Barb Fittings

The RKTB-150 is a 37–43 mm rebolt-style worm gear hose clamp designed for securing 1-1/2" lay flat hose or agricultural poly tubing onto barbed camlock adapters (Type E). In portable irrigation systems, the barb-to-hose joint is a common leak or blowoff point, especially under surge pressure at pump startup. A properly sized, fully tightened rebolt clamp eliminates this failure point and keeps the assembly field-serviceable — the clamp can be loosened and re-tightened without cutting the hose.

Key Features and Benefits

• Wide band design: Distributes clamping force evenly across the hose OD, preventing the localized cutting that narrow-band clamps cause on lay flat and poly hose walls.
• Rebolt (worm gear) mechanism: Single-screw tightening allows precise, repeatable clamping force — tighten with a standard screwdriver or nut driver. Re-tightenable after initial compression set without replacing the clamp.
• Sized for 1-1/2" barb assemblies: Clamp range of 37–43 mm is matched to the OD of 1-1/2" lay flat hose on a 1-1/2" barb — eliminates guesswork when ordering clamps to accompany RKE-150 or RKE-150P Type E fittings.
• Field reusable: Unlike crimp fittings, the rebolt clamp can be removed and reinstalled when the hose needs to be repositioned, shortened, or replaced — reducing replacement fitting costs during the season.
• Compatible with aluminum and polypropylene barbs: Works with both 1-1/2" aluminum (RKE-150) and polypropylene (RKE-150P) Type E camlock adapters.
