The Robertshaw® 2374 Series Adjustable Air Sensing Switches are designed to replace a wide variety of air sensing switches found in residential and light commercial applications including furnaces, electronic air cleaners and humidifiers. Two models are currently available with adjustable ranges. Both models are provided with an SPDT switch that can be actuated by positive or negative pressure or by pressure differential. Highly accurate, these switches are practically insensitive to temperature change with an operating temperature range of -40°F to 190°F (-40°C to 88°C). Each switch includes mounting hardware and an adjustment tool for easy installation and calibration.

GASKET & THREAD SEALANT
Nylog Red is an elastic fluid made from synthetic refrigeration grade compressor oil. Nylog Red is fully miscible and compatible with mineral oil refrigerants and oils. Gaskets coated with Nylog will never dry or become heat fixed to the surface. Threaded connections coated with Nylog will block high pressure leaks by forming a hydraulic seal. Nylog can be used an assembly lube when installing shaft seals, o-rings, schraeder valves, ball valves, or other internal system components.

Features:

Attacks Corrosion: Frees bolts, fasteners and other mechanical components
Removes Rust and Carbon Deposits: Will not attack or damage metal
Penetrates Faster: Penetrates quicker and deeper than similar products
Works Everywhere: Use on any corroded threads or tight parts
Simplifies Repairs: Makes the toughest maintenance jobs easier, faster and safer to execute.
Penetrates Deeper: Penetrates the smallest spaces, threads and openings
Details:

Loosen frozen metal parts the professional way, with Kroil original penetrant in liquid and aerosol (formerly Aero Kroil) formulas. Discover why this is the best penetrating oil to loosen bolts in various applications. When it comes to freeing corroded items in tough spaces, nothing rivals powerful, industry-proven Kroil penetrating oil. Used and trusted by pros and experienced DIYers alike since 1939, Kroil quickly loosens rusted nuts and bolts, frees frozen shafts, pulleys, and more. No space is too tight to reach, thanks to Kroil's ability to penetrate the smallest opening, thread or crevice. Corrosion meets its match, as Kroil removes and prevents rust, cleans and lubricates, and displaces moisture.
