Ask A Question

Description & Features

Manufactured from high-quality 304 stainless steel this constant torque clamp is engineered for hose diameters ranging from 1 to 1-1/8 inches. Its robust construction includes a 5/8-inch wide stainless steel band and internal liner that safeguards soft or silicone hoses from damage.

The extended adjustment range ensures compatibility with hose ODs from 1.00 to 1.75 inches making it suitable for sealed systems and areas with limited accessibility. The clamp's Belleville spring washers and screw are made of 410 stainless steel adding to its durability and reliability.

This clamp effectively compensates for "cold flow" and thermal expansion or contraction thanks to its designed torque feature. The visual "Torque Check" feature provides a clear indication when the clamp is correctly installed ensuring ease of use.

Installation is straightforward: the Constant-Torque clamp is properly tightened when the screw tip protrudes beyond the housing by approximately 1/4 inch with nearly collapsed Belleville washer stacks. Utilizing a torque wrench is recommended for achieving the installation torque of 90-125 inch pounds.

Product Questions & Answers (2)

Question by: Harvey G on Sep 29, 2025, 6:38 PM
So, this clamp fits hoses that are actually 1 inch to 1 1/8 inch on the inside, but the outside diameter can be bigger, like up to 1 3/4 inch? Just want to make sure I'm reading that right.
Answer by: Customer Support on Sep 30, 2025, 7:09 PM
That's correct. The clamp is designed for hoses with an inner diameter of 1 to 1-1/8 inches, but it can accommodate outer diameters ranging from 1.00 to 1.75 inches. This extended adjustment range makes it a versatile option.
Question by: Norm M on Jul 10, 2025, 9:30 PM
clamp says it works on 1 to 1-1/8 inch hose ID, but what's the actual OD range it'll fit over? My hose walls are a little thicker than standard.
Answer by: Customer Support on Jul 11, 2025, 9:39 PM
The OD range on this clamp runs from 1.00 to 1.75 inches, so it covers a pretty wide spread. That 7/8-inch adjustment range gives you room to work with hoses that have thicker walls without having to hunt down a different clamp size. As long as your hose OD falls within that window, you're in good shape.
