Description

Overview

Tridon T-Bolt Clamp 17-19mm delivers a secure, high-load clamp for small diameter hose connections in automotive and trailer service work. Unlike a basic worm-drive clamp, the T-bolt design applies force more evenly, which helps seal soft rubber and silicone hoses without chewing them up.

Features

This clamp is built for consistent tension and hose protection, even in tight spaces:

• Rolled edge band and bridge help protect the hose wall during tightening
• Solid trunnions and a straight bolt design support smooth, controlled tensioning
• Wide band construction supports high clamp loads for demanding hose joints
• Hex-bolt tightening suits fast installation with common hand tools

Specifications and Materials

The 17mm to 19mm size range suits small hose outside diameters when measured at the clamp location:

• Clamp range: 17mm to 19mm
• Band width: 16mm
• Band thickness: 0.7mm
• Bolt: M5 x 40mm with 8mm hex head

Tridon specifies a part stainless construction for strength and corrosion resistance:

• Band and bridge: 430 stainless steel
• Bolt: high tensile carbon steel with zinc plating
• Collar and trunnions: carbon steel with zinc plating

For official sizing and selection guidance, refer to the Tridon hose clamp catalogue (PDF) which outlines T-bolt clamp specifications and material grades.
Part number: TTBY17-19P.

Compatibility and Fitment

Confirm the hose OD falls within 17mm to 19mm after the hose is seated on its fitting. Position the band behind the hose bead where applicable, then tighten the bolt gradually so the clamp centres itself as tension rises. As a result, you get more consistent sealing than uneven, one-sided tightening. Tridon T-Bolt Clamp 17-19mm suits applications where a high clamp load matters, but it still relies on correct hose sizing and sound fittings.

Compliance and Safety

Always follow the hose and equipment manufacturer’s guidance for tightening torque and re-check intervals. Re-tension after the first heat cycle because hoses can relax once they warm and cool. Inspect for sharp edges, hose bulging, or clamp distortion, and replace any damaged parts immediately.

Trailer Applications

Workshops use this style of clamp on coolant and heater hoses, small suction or discharge lines, and compact hydraulic or water service hoses fitted to trailer-mounted equipment. Tridon T-Bolt Clamp 17-19mm also works well where vibration and pressure changes demand a steadier clamping load than light-duty clamps.

Cross-reference and Suitability

Manufacturer documentation does not list confirmed interchange part numbers for this specific clamp size and series. Instead, match the diameter range and clamp style to your hose OD and operating conditions, and choose an equivalent only when the specs clearly align.
