NORMA TORRO Black Oxide Stainless Steel Hose Clamp, 9mm Band
This Norma worm drive hose clamp features a 9mm wide band, all stainless steel construction, a stamped inside band, and knurled edges for optimal hose protection.
A versatile 7mm slotted hex drive provides an easy installation with a socket, wrench or screwdriver.
W4 All stainless steel (304) construction gives this clamp a great resistance to corrosion (A minimum of 240 hour salt spray rating)
Applications include fuel lines, vacuum lines, coolant lines, as well as many other sealing connections.
Finish: Black Oxide
- Abrasion resistant, does not peel, chip or rub off
- Reduces friction, prevents galling
- Does not change the strength of the stainless steel
- Practically no dimensional change to base fastener
- The spray applied during the coating process wears off over time, revealing an attractive matte black finish
The black oxide coating per MIL-DTL-13924, Class 4 on 300 series corrosion resistant steel meets 96 hours of resistance in a 5% salt spray (fog) test in accordance with ASTM B117. We recommend using stainless steel installation tools to prevent extraneous rust.
