Ideal T-Bolt Hose Clamp SAE 338

The Ideal 300110338 is a stainless steel T-bolt clamp designed for sealing hose connections with inside diameters between 3 3/8 in and 3 11/16 in. It is sold as a pack of five clamps suited for automotive, industrial or marine plumbing tasks.

Check hose diameter and hex tool fit

Verify that your hose assembly falls within the 3 3/8 in minimum and 3 11/16 in maximum inside diameter range. Ensure a 7/16 in hex driver or socket is available to reach the 75 in-lb install torque specification.

Stainless construction and T-bolt service

The band uses grade 301 stainless steel at 0.025 in thickness and 3/4 in width, while the screw and housing use grade 304 and 301 stainless respectively. The T-bolt mechanism allows high-torque tightening with a standard hex tool for reliable, repeatable sealing.

Questions about this item

Does the pack of five T-bolt clamps include the installation tool or must I buy a 7/16 in socket separately?

The box contains five clamps only; a 7/16 in socket or wrench is required to reach the 75 in-lb install torque and is not included.

How do I know the SAE 338 size will fit my hose with a 3 3/8 in minimum diameter?

SAE 338 covers an inside-diameter range of 3 3/8 in to 3 11/16 in, so measure the hose OD and confirm it falls within that window.

What does the 75 in-lb torque spec mean when I tighten the clamp on the vehicle?

It is the maximum tightening torque for the stainless-steel screw; exceeding it can stretch the 304-grade screw or deform the 0.025 in band.
