## Overview

The Loc-Line Coolant Hose Component features two 5.5-inch segments made from corrosion-resistant blue acetal copolymer plastic. Designed for modular, snap-fit assembly, it withstands temperatures up to 170°F and meets NSF/ANSI standards for potable water safety. Compatible with a wide range of chemicals, this hose segment is ideal for professional coolant, air, and fluid delivery systems requiring reliable, flexible connections.

## Description

The Loc-Line hose component is two hose segments made of blue acetal copolymer plastic for use with coolant. The acetal copolymer plastic resists corrosion and moisture and can be used with acetone, alcohol, ethyl, greases, oils, commercial dish detergents, gasoline, lacquer solvents, and sodium hydroxide. The component has a maximum operating temperature of 170 degrees F. The material meets National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) 14, 51, and 61 specifications for use with drinking (potable) water, and complies with Registration, Evaluation, Authorization of Chemicals (REACH) and Restriction of the Use of Certain Hazardous Substances (RoHS) standards. The component connects to other Loc-Line components by a ball-and-socket design that snaps together for a tight seal.SpecificationsMaximum Pressure, 1/4" Inner Diameter30 psi (up to 110 psi with element clamp)Maximum Flow, 1/4" Inner Diameter250 gallons/hourMaximum Pressure, 1/2" Inner Diameter20 psi (up to 110 psi with element clamp)Maximum Flow, 1/2" Inner Diameter478 gallons/hourMaximum Pressure, 3/4" Inner Diameter10 psiMaximum Flow, 3/4" Inner Diameter1,140 gallons/hourLockwood Products manufactures the Loc-Line modular hose system of low-pressure hose and couplings used for coolant, air delivery, smoke and dust removal, and other applications.

Review: Worked great - Liked the quality. Used it for a flexible connection and it did the job!
Review: Very versatile and compatible with auxfun/3XLR - I’m familiar with locline from CNC machines and aquariums so I recognized it immediately when looking at the extension rod and other pieces for our auxfun adult toy. I was unable to find the “Y” adapter online at a reasonable price or reasonable shipping time. So, I made my own. I used 5-minute epoxy, 1” shrink tubing, and 3XLR connectors I purchased on desertcart. The whole project was easy and relatively inexpensive. You don’t need the loc-line tool for one-time use but if you’re going to be taking things apart and putting them back together frequently I highly recommend it. It requires a fair amount of arm strength to get them together and a screwdriver to create leverage to pull them apart.
