Harsh chemicals, solvents and cleaners that cause other sprayers to fail are no problem for these sprayers. Sprayers dispense 1.4 ml of liquid per squeeze. Nozzle O-ring and piston cup are constructed of synthetic rubber. Nozzle adjusts spray from a mist to a stream. Trigger Sprayers do resist D-limonene. Note: It is the buyer's sole responsibility for testing their formula's compatibility with these sprayers. Some extremely aggressive chemicals may compromise internal seals, resulting in leaks.
