Description
All-316 SS Worm Drive Hose Clamps for Marine, Water Treatment, and Chemical Applications
Product Overview
The G5 series gear clamp is manufactured entirely from Type 316 stainless steel. Band, housing, and screw are all 316 SS. Standard stainless hose clamps typically use 201 or 301 grade steel, which corrodes in salt water, chlorinated water, and chemical environments. The G5 uses 316 across all components for reliable clamping in applications where lower-grade stainless fails. 12 sizes from 5/8" to 4-1/2" nominal. 1/2" wide band. Sold in packs of 10.

To select the right size: measure the outside diameter of the hose or pipe at the connection point. Choose the clamp whose min-max range covers that measurement.
Key Features of G5 Type 316 Stainless Steel Gear Clamps
- All-316 stainless steel construction. Band, housing, and screw are the same grade, which eliminates galvanic corrosion between mixed metals that can cause standard clamps to seize or fail.
- Type 316 contains 2-3% molybdenum, which resists pitting and crevice corrosion from chlorides in salt water, pool chemicals, and road salt.
- 1/2" wide band distributes clamping force across more surface area than narrow-band clamps, reducing the chance of hose damage or extrusion under pressure.
- A worm drive screw allows gradual tightening and retightening without removing the clamp from the hose.
Applications
- Marine: shipbuilding and marine engine repair
- Water and wastewater treatment plants
- Chemical processing and pulp and paper manufacturing
- Underground installations: fire sprinkler systems, swimming pool piping
- Any hose or pipe connection exposed to salt, chlorine, or aggressive chemicals

Frequently Asked Questions
What is the difference between 304 and 316 stainless steel hose clamps?
Both are corrosion resistant, but 316 adds 2-3% molybdenum for resistance to chloride pitting and crevice corrosion. In salt water, chlorinated water, or chemical environments, 304 and lower grades eventually pit and fail. 316 holds up. Most "stainless steel" hose clamps use 201 or 301 grade. The G5 uses 316 for all three components: band, housing, and screw.
Are all stainless steel hose clamps marine grade?
No. "Stainless steel" on a hose clamp label usually means the band is 300-series SS, but the screw or housing may be a lower grade or even carbon steel. Marine grade means all components are Type 316 SS, which resists salt water corrosion. The G5 qualifies because band, housing, and screw are all 316.
What size gear clamp do I need?
Measure the outside diameter of the hose or pipe at the clamping point. Choose the G5 size whose min-max range covers that measurement. If the measurement falls near the edge of a range, go one size up for adjustment room. See the size chart above for all 12 sizes.
Can 316 stainless gear clamps be used on water treatment piping?
Yes. The manufacturer's catalog lists water treatment plants as a primary application for the G5 series. The 316 SS construction handles the chlorine, chemicals, and moisture typical in water and wastewater treatment facilities without corroding.
