Eaton 11030 Compression Tube Sleeve Brass 1/8 Inch Od

Product Description

The EATON 11030 is a brass compression tube sleeve designed to create a reliable, leak-resistant seal in compression-style tube fittings. The sleeve — also called a ferrule — seats between the compression nut and fitting body, deforming slightly under torque to grip the tubing and form a pressure-tight joint. Constructed from brass, it offers solid corrosion resistance in typical plumbing, HVAC, and instrumentation environments. This sleeve is sized for 1/8 inch outside diameter tubing and is sold in a pack of 50, making it practical for contractors and technicians who need spares on hand or are completing multi-point installations.

Compression sleeves like the EATON 11030 are used wherever compression fittings connect copper, brass, or compatible soft-metal tubing in low-pressure plumbing lines, refrigeration sensing lines, pneumatic controls, and instrument tubing runs. Residential and light commercial applications are common, including connections at supply stops, saddle valves, and control line terminations. The 50-piece pack suits service vans, shop stock, or any installation requiring multiple fittings of the same size.

Key Features

• Brass construction provides corrosion resistance and reliable deformation characteristics for a secure seal
• Sized for 1/8 inch OD tubing — a common dimension in instrumentation, refrigeration, and plumbing control lines
• Pack of 50 sleeves supports bulk stocking and multi-connection jobs
• Compatible with standard compression fitting assemblies using a nut and fitting body
• Single-use ferrule design ensures a fresh, undamaged seating surface on every connection

Compatibility

Designed as an OEM-style replacement or service sleeve for standard compression fittings accepting 1/8 inch OD tubing across plumbing, HVAC control, and instrumentation applications.

Installation Notes

Compression sleeves are installed by plumbers, HVAC technicians, and instrumentation trades. Before service, shut off the water, refrigerant, or pneumatic supply pressure to the line being worked. Slide the compression nut onto the tubing first, then the sleeve, before inserting the tube into the fitting body and threading the nut hand-tight followed by a wrench turn per the fitting manufacturer guidance. Do not reuse a previously compressed sleeve, as the deformed ferrule will not seal reliably on a second installation.
