5/16" - 7/8" #6 Stainless Steel Worm Gear Hose Clamp w/ Carbon Screw

The Bluefin HCL6 is a worm gear hose clamp designed to secure hose connections from 5/16 inch up to 7/8 inch in diameter. This #6 size clamp features a stainless steel band paired with a carbon steel screw, delivering corrosion resistance where the band contacts the hose while keeping the fastener affordable and serviceable. It's built for HVAC technicians, plumbers, and maintenance professionals who need a reliable, adjustable clamp for water lines, drain hoses, and light-duty fluid connections. The worm gear mechanism allows precise tightening and re-adjustment without removing the clamp, so you can dial in the exact tension your application demands.

• Stainless Steel Band Construction: The band itself is stainless steel, resisting rust and corrosion where it wraps around rubber or vinyl hose. This means the clamp won't stain your hose or weaken from water exposure, extending service life in damp environments.
• Carbon Screw: The tightening screw is carbon steel, providing strength and a secure grip at a lower cost than all-stainless hardware. For indoor or above-ground applications where the screw isn't submerged or buried, this combination delivers excellent value.
• Adjustable 5/16" to 7/8" Diameter Range: One clamp fits a wide span of hose sizes, reducing the number of SKUs you need to stock. Whether you're clamping a 3/8 inch condensate line or a 7/8 inch washer drain hose, this #6 clamp adjusts to fit.
• Worm Gear Design: Turn the screw to tighten or loosen the band incrementally, giving you precise control over clamping pressure. This design also lets you reuse the clamp if you need to reposition or replace a hose, unlike crimp-style clamps that are one-time use.
• Compact Footprint: The narrow band and low-profile screw housing fit into tight spots behind appliances, under sinks, and in crowded mechanical rooms where space is limited.
• Quick Installation: Slide the clamp over the hose, position it over the fitting, and tighten with a screwdriver or socket. No special tools, no mess, and no callbacks for leaks.

This clamp works with any flexible hose or tubing that falls within the 5/16 inch to 7/8 inch outer diameter range, including PVC, rubber, vinyl, and polyethylene hose. It's commonly used on washing machine drain hoses, dishwasher connections, condensate lines, pool and spa plumbing, and light irrigation repairs. Because the screw is carbon steel, do not bury this clamp underground or submerge it in water for extended periods, as the screw will corrode. For buried or fully submerged applications, use an all-stainless clamp instead.

Slip the clamp over the hose end before pushing the hose onto the barbed fitting or spigot. Position the clamp so the band covers the connection point, then tighten the screw with a flathead or hex-head screwdriver until the hose compresses snugly against the fitting. You should feel resistance but avoid over-tightening, which can damage thin-walled hose. The stainless band requires no maintenance, but if you're working in a humid or outdoor environment, periodically check the carbon screw for surface rust and replace the clamp if the threads show significant corrosion.

A: No, this clamp is not rated for burial. The carbon steel screw will corrode when exposed to soil moisture, even at shallow depths. The rate of deterioration depends on your soil composition, but underground use is not recommended. For buried applications, choose an all-stainless clamp with a stainless screw.

A: The Bluefin HCL6 adjusts from a minimum of 5/16 inch to a maximum of 7/8 inch outer diameter. This fits hose sizes commonly found on appliance drains, condensate lines, and small irrigation connections.
