Heavy-duty Metal Lantern Hoop Galvanized Steel Rubber Lined One-Screw Pipe Clamp Casing Epdm Rubber Tubing with Hose Clamps

Lantern Hose Clamp

The lantern hose clamp is a hose fastening fixture shaped like a lantern (bulging in the middle), with core features of uniform pressure application and strong anti-twist capability. It is suitable for scenarios requiring high sealing performance and hose protection.

Structure and Principle

Key Design

- Drum-shaped steel strip: The middle of the steel strip bulges outward (with a diameter larger than both ends), forming a "lantern" shape. When tightened, it applies uniform radial pressure to the hose.
- Worm gear drive: The steel strip is tightened by rotating the worm gear, providing stable clamping force that can be precisely controlled via scales or a torque wrench.
- Materials: Commonly made of stainless steel (mainly 304) or galvanized carbon steel, with a smooth, burr-free surface to avoid scratching hoses.

Size List

Advantages

- Strong Hose Protection: The drum-shaped design distributes clamping force, reducing the risk of hose damage by over 70%.

- Uniform Sealing: Consistent radial pressure lowers leakage rates by 50% compared to ordinary hose clamps, making it ideal for low-pressure precision systems.

- Easy Installation: No professional tools required; manually operable via a worm gear knob for quick on-site installation.

Selection and Usage Recommendations

1. Choose by Hose Material

- Rubber hoses: Prioritize stainless steel lantern hose clamps for corrosion resistance and a smooth contact surface.

- Plastic hoses: Galvanized carbon steel is suitable to avoid scratching the pipeline with过硬 materials.

2. Pressure Matching

- Low-pressure scenarios (≤0.5MPa): Use standard models directly; for high pressure, pair with rubber gaskets to enhance sealing.

3. Installation Tips

- Ensure the clamp's middle aligns with the hose interface center to avoid uneven force from skewing.

- Tighten moderately so the hose slightly deforms but is not crushed (reference torque: 8–15N·m).

For special working conditions (e.g., high temperature, strong corrosion), select stainless steel clamps with silicone rubber coatings or consult suppliers for custom thickened steel strip models.
