HERCULES

HERCULES leak detection fluids, such as the 8 oz dauber bottle (MPN 45801) and the 32 oz spray bottle (MPN 45802), are rated for a temperature range of -50°F to 200°F. This range covers typical ambient conditions in industrial gas piping, valve, and fitting applications. The fluid is blue in color and forms bubbles at leak sites to indicate escaping gas. The dauber bottle allows for pinpoint application, while the spray bottle covers larger areas. Both are intended for use on gas systems where bubble formation can visually confirm leaks. The temperature rating should be considered when applying the fluid in extreme hot or cold environments, as performance may vary outside the specified range.

HERCULES coolant and antifreeze test strips (SKU 53JW81) measure pH levels from 0 to 8.5. Each pack contains 10 strips. These strips are designed for corrosion protection testing in propylene glycol systems. The pH measurement helps maintenance personnel assess the condition of coolant or antifreeze, as pH can indicate the level of corrosion inhibitors or the presence of degradation products. The strips provide a quick, on-site method for checking pH without laboratory equipment. The 0 to 8.5 range covers the typical operating pH of many coolant formulations, where deviations can signal the need for fluid replacement or additive adjustment. The strips are single-use and come in a pack of 10, suitable for routine monitoring.

HERCULES ProPoxy 20 is a gray, epoxy-based plumbing repair putty supplied in a 4 oz tube (MPN 25515C). It is formulated for sealing leaks, cracks, and holes in pipes, fittings, and fixtures. The putty cures to a water-resistant finish, making it suitable for both emergency and permanent plumbing repairs. It can be applied to wet or dry surfaces, depending on the specific product instructions. The epoxy base provides adhesion and durability once cured. Typical applications include repairing copper, PVC, and steel pipes, as well as sealing joints and fixtures. The 4 oz tube size is convenient for small to medium repairs. As with any epoxy putty, surface preparation and cure time should be followed according to the manufacturer's guidelines to achieve optimal results.

HERCULES roofing sealers and primers are available in three container sizes: a 10.3 oz tube (MPN 25403), a 1-quart pail with resealable lid (MPN 25405), and a 1-gallon pail with resealable lid (MPN 25410). All are black in color. The tube format is suited for sealing joints, flashing, and cracks in roofing systems, while the pail formats are intended for larger areas or multiple applications. The resealable lid on the pails helps extend product life after opening. These sealers and primers are used for maintenance and repair of roofing surfaces to prevent leaks and weather damage. The choice of container depends on the scale of the repair and the application method—tube for precise bead application, pails for brush or trowel application over broader areas.

HERCULES leak detection fluids are designed for locating leaks in gas piping, fittings, and valves. The product descriptions do not specify compatibility with specific gas types, but they are commonly used on natural gas, propane, and compressed air systems. The fluid works by forming bubbles at the leak site, which is a physical indication of escaping gas. It is important to verify compatibility with the specific gas and system materials before use, as some gases may react with the fluid or require specialized detection methods. The temperature range of -50°F to 200°F should be observed. For any application involving flammable gases, follow appropriate safety procedures and consult the manufacturer's technical data for guidance.

The product information for HERCULES coolant and antifreeze test strips (SKU 53JW81) does not specify a shelf life. Test strips generally have a limited shelf life, and exposure to moisture or contaminants can affect accuracy. It is recommended to store them in a cool, dry place and to check the expiration date if provided on the packaging. Each pack contains 10 strips, and they should be used within a reasonable period after opening. For critical pH monitoring, always use strips before any printed expiration date and follow the manufacturer's storage instructions. If no date is given, rotate stock and avoid using strips that appear discolored or damaged.
