A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.

Designed for ultra-clean environments, these manifolds are cleaned, dried, and vacuum sealed in plastic to prevent dirt and moisture from contaminating the inside. Use them to distribute air or fluid to multiple locations from a single supply source. Also known as headers.

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant permanent connection.

Joints are for two-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

Use in medium-pressure applications up to 600 psi.

Use in high-pressure applications up to 1,000 psi.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

Use with soft plastic tubing to prevent the tube from collapsing.

These fittings have the highest pressure rating of all the Yor-Lok tube fittings we offer.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Use these rings with quick-clamp high-vacuum fittings.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Fittings are polished to a32 Ra and under finish on the interior.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

The external hex bolt on these fittings allows for easy installation in cramped spaces.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.
