Take liquid samples in sanitary environments—these sampling valves have a hygienic design, so they’re commonly used in breweries and wineries. With a body made of 316 stainless steel and a PTFE plastic seat, they resist the high temperatures and harsh chemicals of clean-in-place (CIP) processes. These valves have an extremely smooth surface, leaving no space for bacteria to grow. Quick-clamp connections, also known as tri-clamp fittings, are easily taken apart for regular cleaning. These valves are self-draining, so previous samples and cleaning chemicals won’t contaminate future samples. Both the seat and the silicone O-ring comply with FDA standards for direct contact with food and beverage.

To take samples, turn the thumb screw to open valves. Hang a bucket for sample collection from the bucket groove. Valves also have a leak detection port that will release a small amount of liquid to let you know when it’s time to replace all the valve seals.

Valves with a bent spout have a tab for connecting carbon dioxide testing devices. They’re often used for carbonated beverages. They shouldn’t be used with liquids that have solids in them, such as the grape skins or seeds in wine, as those can get caught in the outlet.

To test water quality without interrupting flow, turn the handle to drain a small amount of liquid through the sampling outlet. These valves cannot shut off flow. All are standard port, so they slightly restrict flow.

Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them. Made of 316L stainless steel, they’ll stand up to harsh cleaners and sanitizers without corroding. They also have polished internal surfaces, minimizing the space where bacteria could grow. With quick-clamp connections, they are easy to take apart for cleaning or reconfiguring your line. All are 3-A certified to meet sanitary design standards, so they’re often used in food and beverage, pharmaceutical, and biotech applications.

All fittings require pierceable lids (sold separately) to draw samples through a hypodermic needle. Each lid is good for seven samples, and each sample leaves a hole mark, so you know when it’s time to unscrew the nut on the tube fitting and swap in a new lid. To help prevent dust and moisture from accumulating on the lid, all tube fittings have a dust cover. These lids are FDA compliant, so they keep contaminants from entering your line and also are approved for direct contact with food if they break off and fall in. Manufactured free of contaminants and allergens, all are BPA-, latex-, and phthalate-free. They’re also TSE/BSE compliant, meaning they’ve never come into contact with any animal products.

Pair these tube fittings with liquid samplers for a sample. They use gravity to draw out liquid through the needle directly into the bag.
