Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position. All of these plungers have a long nose that offers a large bearing surface to handle side loads. They’re often used for maintenance jobs.

Made of stainless steel, these plungers won’t corrode from frequent washdowns with harsh cleaners and sanitizers. All are self-draining with rounded edges and polished surfaces, so there are no crevices for bacteria to grow, reducing the chance of a foodborne illness. Seals block out water and keep contaminants from getting trapped in threads or grooves. They’re also bright blue, so you can easily spot broken pieces that fall into your line. The seals are FDA compliant for direct contact with food, but the lubricant is rated for incidental contact.

Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Lock the nose into the retracted position by pulling the ring and rotating it 90°. The ring allows you to attach these spring plungers to a lanyard to secure them to machinery and prevent accidental drops. They have a long nose that provides a large bearing surface to handle side loads.

Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments.

18-8 stainless steel is chemical resistant.

Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.

Spring plungers with thread locker have a locking patch that adds friction to resist loosening.

Install from the nose end without depressing the nose using a driver (sold separately). With a nose that is longer than a ball-nose, these provide a large bearing surface to handle side loads.

Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.

18-8 stainless steel is chemical resistant.

Plastic is chemical resistant and lightweight; acetal noses are extra soft to minimize marring soft surfaces such as aluminum.
