Pack of ten zinc-coated steel constant-tension band clamps, 17 mm nominal size

Zoro Select

Zoro Select CTB-17ST Constant-Tension Band Clamp 17mm PK10

SKU CH-BZQZ-BNCJK

Pack of 10 constant-tension steel band clamps with 17 mm nominal size and 15 mm band width

  • Constant-tension design maintains secure seal on 17 mm hose
  • Zinc-coated SAE 1074 steel band resists corrosion
  • 85 mm band thickness balances strength and flexibility
  • Clamping range 15.2 mm to 18.5 mm fits nominal 17 mm applications
  • Pack of 10 clamps meets SAE J1508, REACH and RoHS standards

17 mm Constant-Tension Band Clamp Pack

This pack contains ten zinc-coated steel band clamps designed for 17 mm nominal hose and tube sizes. The constant-tension design maintains sealing pressure as temperatures cycle. Each clamp meets REACH, RoHS and SAE J1508 standards. Builders and technicians use them for fluid and vacuum connections in automotive and workshop systems.

SAE 1074 Steel with 0.85 mm Band Thickness

The band is made from SAE 1074 grade steel and measures 15 mm wide by 0.85 mm thick. Zinc coating adds corrosion resistance for long service life. The constant-tension mechanism compensates for hose expansion and contraction without retightening. Ten clamps per pack support multiple connections or spares.

Check Hose ID Before Ordering

Verify that your hose or tube inner diameter falls between 15.2 mm and 18.5 mm for proper clamp engagement. The clamp is sized for 17 mm nominal applications only. Ensure the band width and thickness suit the available installation space. No additional hardware or tools are included in the package.

Questions about this item

Will the zinc-coated steel bands on these 17 mm clamps need periodic re-tensioning or replacement?

The constant-tension design maintains clamping force as hose materials expand and contract with temperature cycles, reducing the need for manual re-tensioning; zinc coating on the SAE 1074 steel resists corrosion to extend service life.

What is the smallest hose diameter these 17 mm clamps can seal effectively?

The minimum inside diameter is 15.2 mm; hoses smaller than this will not engage the band fully and may leak under pressure.

How much heat can the band material withstand before the zinc coating degrades during all-day operation?

SAE 1074 spring steel retains its tension properties well above typical automotive coolant temperatures, and the zinc coating remains protective within normal engine-bay heat ranges.
