Dual Bead Constant Tension Hose Clamp
The DISLAB PRECISION dual bead constant tension hose clamp combines a stainless steel worm-drive structure with a shaped inner lining that concentrates sealing pressure along two contact zones. It is designed for soft hose connections exposed to temperature changes, vibration and repeated expansion or contraction.
- W4 Stainless Steel
- 12.7 mm Band Width
- M8 Screw
- 10–254 mm Size Range
Controlled Sealing Pressure for Soft Hose Connections
A conventional flat band can concentrate pressure at the housing or allow the clamp to move when a hose changes diameter. The dual bead inner profile is designed to improve sealing contact, resist slipping and reduce direct contact between the perforated outer band and the hose surface.
Dual-Bead Sealing Profile
Two raised inner contact lines direct clamping force toward the sealing area, helping create more consistent pressure around the hose circumference.
Constant Tension Support
The structure helps maintain a stable clamp load as soft hoses shrink, expand or settle during thermal cycling and normal equipment operation.
Soft Hose Protection
The inner lining separates the hose from the perforated worm-drive band, reducing the risk of cutting, pinching or marking sensitive hose materials.
Stable Under Vibration
The worm-drive housing, M8 screw and shaped stainless steel band provide secure adjustment for vehicle, machinery and industrial hose assemblies.
What This Hose Clamp Is Designed to Solve
Soft coolant, air-intake and turbo hoses can change diameter as temperature and pressure fluctuate. Ordinary clamps may leave uneven pressure areas, loosen after repeated cycling or damage the hose near the band slots.
- Helps control leakage caused by hose shrinkage and thermal movement.
- Reduces direct contact between the perforated band and the hose surface.
- Improves resistance to clamp movement on smooth or flexible hoses.
- Provides adjustable worm-drive installation for maintenance and assembly.
- Supports commercial vehicle, passenger vehicle and industrial hose systems.
Designed for Consistent Hose Sealing
The dual bead design places band-sealing pressure where it is needed instead of applying only a broad, flat load. This makes the clamp particularly useful where hose protection and stable sealing are both important.
Final clamp selection should consider the actual hose outside diameter, hose material, operating temperature, pressure, vibration level and installation torque.
Hose Diameter Changes
Temperature cycles can cause rubber and silicone hoses to expand, contract or take a permanent set.
More Stable Clamping Load
The constant tension structure helps compensate for normal hose movement and supports a more consistent seal.
Band-Slot Hose Damage
A perforated outer band may mark or cut softer hose surfaces when installed without a protective lining.
Protected Contact Surface
The smooth inner lining distributes contact and isolates the hose from the worm-drive band perforations.
Dual-Bead Lining and Worm-Drive Adjustment
The clamp consists of a stainless steel outer band, screw housing, M8 adjustment screw and a formed inner lining. The lining creates the characteristic dual-bead contact profile while covering the perforated section of the outer band.
W4 Stainless Steel Configuration
The W4 configuration uses stainless steel components for the band, housing and screw. According to the available product information, the clamp can be supplied with SS201 or SS304 components based on the confirmed order specification.
- Stainless steel outer worm-drive band
- Stainless steel screw housing
- M8 adjustment screw
- Dual-bead stainless steel inner lining
- Corrosion-resistant construction for demanding environments
Material Confirmation
SS201 and SS304 provide different corrosion-resistance and purchasing cost levels. Confirm the required stainless steel grade, operating environment and expected service conditions before production.

Dual Bead Constant Tension Hose Clamp FAQ
How is a dual bead hose clamp different from a standard worm-drive clamp?
A standard worm-drive clamp normally places a flat perforated band directly against the hose. This product includes a shaped inner lining with two raised contact areas. The lining helps distribute sealing pressure and prevents the perforated outer band from directly contacting the hose surface.
Is this clamp suitable for soft rubber or silicone hoses?
It is designed for soft hose applications such as coolant, air-to-air and intake hose connections. The correct clamp range and installation torque must still be selected according to the hose material, wall thickness and operating conditions.
What does W4 mean for this hose clamp?
W4 indicates a stainless steel clamp configuration. The supplied product information lists stainless steel construction for the band, screw and housing, with SS201 or SS304 available according to the confirmed order specification.
What standard sizes are available?
The listed standard clamp ranges start at 10–16 mm and extend to 228–254 mm. Other sizes may be discussed according to customer requirements and production feasibility.
Can the clamp be used under vibration and temperature cycling?
The constant tension and dual-bead structure is intended to improve sealing stability when a hose is exposed to vibration, temperature change and normal expansion or contraction. Actual suitability should be checked against the operating temperature, pressure, hose material and installation conditions.
What information is required for an accurate quotation?
Provide the hose outside diameter, required clamp range, material grade, operating environment, order quantity and packaging requirement. Photos, drawings or an existing clamp sample can also help confirm the correct configuration.
