• High-quality stainless steel material, excellent rust and corrosion resistance, suitable for humid and high-temperature engine compartment environment.
• Smooth band edge design, avoid sharp edge cutting the rubber hose during installation, protect the hose outer layer and extend hose service life.
• Worm drive stepless adjustment, clamping diameter 51-70mm, wide adjustable range, can fit different hose outer diameters within this interval.
• Uniform clamping force distribution after tightening, the hose will not be locally crushed, forming reliable sealing effect at hose joint.
• Compact and lightweight structure, quick installation and disassembly, convenient for maintenance work in narrow space inside engine compartment.
• Stable mechanical performance under temperature change and cyclic vibration, clamping force will not drop easily after long time operation.
• OEM dimensional standard, match perfectly with original hose assembly, no modification required during installation.

FAQ 

Q：What signs mean the hose clamp needs replacement?
A：Serious rust and pitting on clamp surface, worm screw stuck and cannot adjust, band fracture, clamping force failure, hose joint leakage caused by clamp aging.

Q：What should be noted during hose clamp installation?
A：Align hose and pipe joint first; place the clamp at the middle position of hose bell mouth; tighten screw with recommended torque, do not over-tighten. Keep the clamp away from sharp parts to avoid friction damage.

Q：What are common causes of hose clamp damage?
A：Long-term damp environment leading to rust; excessive tightening torque causing band deformation; friction with surrounding metal parts; high temperature aging of worm screw assembly.

Q：Can rusted hose clamp be reused?
A：Not recommended. If there is serious corrosion or the worm screw is stuck, the clamping force cannot be guaranteed. Replace with new hose clamp directly to prevent sudden leakage.

Q：How to inspect hose clamp during daily maintenance?
A：Check clamp tightness and surface corrosion before heavy-load operation. Focus inspection on screw and band, these areas are most prone to rust and failure.

Q：What failures will a failed hose clamp cause?
A：Damaged or loose hose clamp cannot hold the hose tightly, leading to coolant leakage at hose joint, which may cause engine overheating and equipment shutdown.

Q：Can this hose clamp fit hoses beyond 51-70mm?
A：This hose clamp’s adjustable range is 51-70mm. It cannot clamp hoses with outer diameter out of this range. Wrong selection will lead to insufficient clamping force and leakage.
