Precision Brand 33040 Miniature Stainless Hose Clamp

Product Description

The PRECISION BRAND 33040 is an all-stainless miniature worm gear hose clamp designed to create a tight, lasting seal on small-diameter hoses and tubing. The M6S Micro Seal construction accommodates clamping ranges from 5/16 inches to 7/8 inches, making it well suited for confined spaces where standard-size clamps cannot fit. The all-stainless steel build resists corrosion and maintains clamping force under vibration, preventing the clamp from working loose over time. Licensed tradespeople and experienced DIYers install this clamp as a reliable fastening solution in a variety of fluid-handling applications.

This clamp is used across plumbing, HVAC, and general mechanical service work wherever small-bore hose connections require a secure, vibration-resistant seal. Typical applications include fuel lines, air lines, and fluid lines in tight equipment bays or behind panels where access is restricted. Its compact profile allows installation in spaces that would be inaccessible to full-size worm gear clamps.

Key Features

• Miniature all-stainless steel worm gear construction resists corrosion in wet or chemical-exposed environments
• Clamping range of 5/16 inches to 7/8 inches fits small-diameter hoses and tubing
• Low-profile design installs in very tight spaces with limited tool clearance
• Maintains clamping force under vibration without loosening
• Suitable for fuel lines, air lines, and fluid lines

Compatibility

Designed as an OEM-style replacement or service clamp for small-diameter hose and tubing connections in plumbing, HVAC, and mechanical fuel or fluid line applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical service professionals. Before installing, shut off all fluid or air pressure to the line being serviced and depressurize the system fully. A flat-head screwdriver or a small nut driver is sufficient to tighten the worm gear drive. Do not overtighten, as excessive torque on small-diameter tubing can cause deformation of the hose at the clamp seat.
