Hose Clamp Size and Pipe Diameter Comparison Chart

Note: The hose clamp size is matched according to the outer diameter of the pipe. The following is a universal selection chart, covering common metric and imperial specifications, suitable for most industrial and household scenarios.

I. Common Hose Clamp & Pipe Diameter Comparison (Metric/Imperial)

Hose Clamp Size (mm)	Suitable Pipe Outer Diameter (mm)	Corresponding Pipe Size (Inch)	Band Width (mm)	Application Scenarios
8–12	8–12	1/4" (2分)	6/8	Oil pipes, air pipes
10–16	10–16	3/8" (3分)	8	Gas pipes, natural gas pipes
13–19	13–19	1/2" (DN15, 4分)	8	Household small water pipes
16–25	16–25	3/4" (DN20, 6分)	8	Standard water pipes
19–29	19–29	1" (DN25)	8/12	Universal water pipes
22–32	22–32	1.2" (DN32)	12	Medium-sized pipes
25–38	25–38	1.5" (DN40)	12	Industrial pipes
32–44	32–44	2" (DN50)	12	Large-diameter water pipes
40–57	40–57	2.5" (DN65)	12	Industrial pipelines
50–70	50–70	3" (DN80)	12	Large-scale pipes
60–80	60–80	4" (DN100)	12	Municipal/Industrial use
70–90	70–90	5" (DN125)	12	Heavy-duty pipelines
80–100	80–100	6" (DN150)	12	Extra-large pipes

II. Common Imperial Hose Clamp Specifications (Inch/Metric)

Imperial Size	Metric Range (mm)	Band Width (mm)
7/32"–5/8"	6–16	6
7/16"–3/4"	11–20	6
1/2"–7/8"	13–23	6
1/2"–1"	13–25	6
1/2"–1 1/4"	18–32	6
13/16"–2"	21–38	8
13/16"–1 3/4"	21–44	8
15/16"–2 1/4"	35–57	8
1 9/16"–2 1/2"	40–63	10
2 1/16"–3"	52–76	10
4 5/8"–5 1/2"	118–140	12
5 1/8"–6"	130–152	12

III. Selection Notes

Based on Outer Diameter: The hose clamp is selected according to the outer diameter of the pipe, not the inner diameter.
Leave Adjustment Margin: The pipe diameter should preferably fall in themiddle section of the hose clamp's adjustable range for more stable locking.
Band Width Matching: Use 6–8mm band width for small-diameter pipes and 10–12mm band width for large-diameter pipes to ensure even pressure distribution.
Material Selection: Choose201 stainless steel for general scenarios; select 304/316 stainless steel for high-pressure or corrosive environments to enhance durability and corrosion resistance.
