Right-Angle Flow Rectangular Manifolds
Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side.
PTFE manifolds have the best chemical and corrosion resistance of all the plastic and metal manifolds we offer, so they’re the best choice for acids and other highly corrosive substances. Do not use with deonized water at temperatures above 120° F.
Use a plug (sold separately) to close off any unused inlets and outlets.

Easy-Fit Barbed Hose Fittings for Chemicals
Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp. Fittings are 316 stainless steel, which has excellent corrosion resistance to withstand a variety of chemicals.
Adapters are also known as hose nipples; they adapt a barbed end to a threaded end. Adapters with a hex body can be tightened with a wrench.

Through-Wall Fittings for High-Vacuum Chambers
- For Use With: See table
- Environment Temperature Range: 32° to 300° F
- Process Temperature Range: -325° to 995° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: See table
Also known as feedthroughs, these fittings transfer liquids, cryogenic liquids, or gasses into high-vacuum chambers for coating, cooling, and leak-testing applications without losing vacuum pressure. Consisting of high-vacuum fittings, metal tubing, and Yor-lok tube fittings, these complete assemblies come ready to install. The quick-clamp (KF) or flanged (CF) high-vacuum fittings form a tight seal on chamber walls. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing for a leak- and gas-tight connection. The entire assembly is stainless steel so it resists rusting. Not for use in pressure applications.
Quick-clamp fittings meet ISO (International Standards Organization) 2861, which specifies the dimensions of quick-clamp high-vacuum fittings, clamps, and rings to ensure vacuum tightness. These fittings require a clamp and ring (each sold separately) to complete the connection.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.

Pipeline Fluid Blockers
Also known as paddle blinds, these fit between two flanges to temporarily block the flow while you work downstream.
304 stainless steel blinds are more corrosion resistant than steel blinds.
