Quick-Connect High-Vacuum Fittings for Stainless Steel Tubing
Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools. To connect, insert your tubing into the fitting and twist the collar on the end of the fitting; an O-ring on the inside of the fitting compresses to form the seal. Also known as quick-disconnects, they're as easy to twist off as they are to twist on. Not for use in pressure applications.
Connectors have quick-connect fittings on both sides. Use them to connect two lengths of tubing: stainless steel to stainless steel, glass to glass, or go from one material to the other.
Adapters have a quick-connect fitting on one side and a quick-clamp fitting on the other. Use them to attach and remove components for one-off uses or to adapt your quick-clamp system to connect to glass tubing. Quick-clamp fittings are also known as KF, QF, and NW fittings; they require a clamp and ring (sold separately) to complete the connection.

Vacuum Fittings for Steel Tubing
- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: -10° to 180° F
- Tubing: Galvanized Steel: Use with steel, galvanized steel
Steel: Use with steel
Use these fittings to create an air vacuum system without the hassle of brazing and welding. Insert two fittings into a clamp (sold separately) and tighten to form a secure seal.
Galvanized steel fittings have fair corrosion resistance. Fittings without a finish should only be used in noncorrosive environments.

Fiberglass Pipe Flanges for Corrosive Chemicals
- For Use With: Acetic Acid (75%), Alcohol, Calcium Chloride, Chlorine, Fuel Oil, Gasoline, Hydrochloric Acid (37%), Nitric Acid (10%), Oil, Phosphoric Acid, Salt Water (30%), Sodium Hydroxide (50%), Solvents, Sulfuric Acid (70%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D4024
Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.
To connect flanges to pipe, first sand the inside of the flange and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8” thick. Repeat this process with the inside of the flange, applying a layer approximately 1/16” thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

- Compatible with Gravity-Flow Polypropylene Pipe for Corrosive Chemical Waste
Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies. All meet UL and ASTM standards for flame retardance and self-extinguishment in the case of fire. They also meet strict ASTM specifications and testing requirements for material quality and product dimensions. They’re compatible with Orion Blueline No-Hub and Orion Rionfuse chemical waste pipe and pipe fittings.
Adapters for glass pipe connect to older glass piping systems with a bead-to-bead clamp (not included).
