Aluminum Female Cam‑Lock Coupler with Eccentric Variable Diameter Hose Tail for Fluid Systems
The Aluminum Female Cam‑Lock Coupler with Eccentric Variable Diameter Hose Tail is a specialist adapter designed to bridge connections between standard Cam‑Lock female fittings and hoses of differing diameters in industrial fluid handling applications. Engineered for systems where direct alignment between pipeline and hose is not practical, this eccentric variant improves flow dynamics and installation flexibility while maintaining the trusted performance of a Cam‑Lock connection.
Material and Construction
This series features an aluminum body that keeps the assembly lightweight yet robust, offering excellent resistance to corrosion and extended service life in demanding environments. The solid brass handles ensure reliable operation and enhanced mechanical strength; brass resists wear and reduces the risk of fracture during engagement or disengagement, enhancing operator safety. The gasket is made from Buna‑N (nitrile rubber), providing effective sealing for a wide range of fluids including water, fuel, and most industrial liquids at up to 0.6 MPa working pressure.
Eccentric Hose Tail Design – What It Means and Why It Matters|
Unlike standard concentric adapters where the centerlines of both ends align, the eccentric design shifts the hose tail’s centerline relative to the female Cam‑Lock coupling. This offset has several practical advantages, especially in real‑world fluid systems:
1. Eliminates Low‑Point Accumulation
In piping systems, concentric reducers can create a low spot where sediment, debris, or condensate can collect. Eccentric connections prevent this by maintaining an uninterrupted top or bottom flow profile, reducing the risk of buildup that can lead to clogging or contamination.
2. Improved Drainage and Self‑Draining Capability
When installed with the flat side up (for top alignment) or flat side down (for bottom alignment), an eccentric adapter enables better gravity‑driven drainage. This is especially useful in fuel dispensing lines, loading arms, or any system where residual fluid must be minimized after shut‑off.
3. Better Alignment in Restricted Spaces
Because the hose tail does not sit directly in the same centerline as the Cam‑Lock female fitting, the eccentric design can accommodate changes in elevation or lateral offset without causing excessive bending or stress on hoses, reducing fatigue and extending hose life.
4. Reduced Turbulence and Flow Resistance
In applications where liquids transition between different diameters, the offset can help streamline flow, minimizing turbulence at the transition point. While the effect may be subtle in low‑velocity systems, it becomes beneficial in higher flow rate situations, reducing energy loss and improving overall efficiency.
Standard Sizes Available
We stock several commonly used eccentric configurations to suit a variety of installations:
ALFEEHT‑250‑100: 2.5″ Female x 1″ Hose Tail
ALFEEHT‑250‑125: 2.5″ Female x 1.25″ Hose Tail
ALFEEHT‑300‑100: 3″ Female x 1″ Hose Tail
ALFEEHT‑300‑125: 3″ Female x 1.25″ Hose Tail
ALFEEHT‑300‑150: 3″ Female x 1.5″ Hose Tail
These models are manufactured to match standard Cam‑Lock dimensions and perform seamlessly with existing systems. If unique sizes or non‑standard configurations are required, custom production can be arranged based on order specifications and application details.
