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.

Spring plungers with a sealing nut can be held in place with the nut after threading them to your desired depth. The nut completely covers the threads and has two seals to block out water and other contaminants.

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.

Thread these sanitary knobs into holes so you can open doors and drawers in hygienic environments. They’re commonly used on furniture and equipment in pharmaceutical and food-processing facilities. Made of Buna-N rubber, the seal keeps out contaminants and blocks unhygienic metal-to-metal contact. It’s FDA compliant for direct contact with food, and blue for easy spotting and removal if it falls into your line. Knobs have a 316 stainless steel body, so they resist corrosion from frequent washdowns with harsh cleaners. Highly polished, with rounded edges and no horizontal ledges, they leave no room for bacteria to grow.

With a sanitary design, these threaded-hole knobs are often used to open and close doors and drawers on furniture, machines, and other equipment in pharmaceutical and food-processing facilities. They attach like most knobs in your kitchen—push a screw through the back of a hole and thread these knobs onto the front. The seal is blue, so it’s easily seen and removed if it falls into your line. It’s also FDA compliant for direct contact with food. Knobs have a 316 stainless steel body that resists corrosion from frequent washdowns with harsh cleaners.
