Vibration-Resistant Water Hose with Flanges
- Temperature Range: -50° to 800° F
- Maximum Vacuum: 28" of Hg @ 72° F
- Material: 304 Stainless Steel
Also known as pump connectors, hose is sized to specific lengths for attaching to pumps. Its flexible braided construction absorbs vibration to reduce wear on equipment. To connect hose, bolt two same-size flanges together. You will need a gasket to complete the seal.

Ultra-High-Vacuum Hose with Flanges
Often found in semiconductor manufacturing and other demanding industrial applications, this hose handles nearly perfect vacuum. Sharp edges on the flanges dig into a copper gasket (sold separately) as you bolt the flanges together, creating a tighter seal than fittings with a rubber gasket. This allows the hose to maintain the ultra-high vacuum necessary for vacuum coating, heat treating, leak testing, and analyzing gases. The flanges are commonly referred to as ConFlat (CF) and UHV fittings. Thanks to its ribbed interior, this hose is flexible enough to connect misaligned components. That's why it's also called a bellows. The ribbing reduces vibration between components, such as vacuum pumps, valves, and chambers. Both the hose and flanges are made of stainless steel, so they resist rusting.
One of the flanges rotates, so you can easily match up the bolt holes with another flange. Make sure your mating flanges are the same size as these flanges.
Bolt kits are required to make a complete connection.

Vibration-Resistant Chemical Hose with Flanges
- Temperature Range: -65° to 500° F
- Maximum Vacuum: 29" of Hg @ 72° F
- Material: 304 Stainless Steel with PTFE Liner
- Both Fittings Swivel Until Tightened
Transfer harsh chemicals while reducing vibration that could damage pumps or other equipment. This hose is made of corrugated stainless steel and reinforced by a stainless steel braid, so it absorbs vibration instead of passing it on. Also known as a pump connector, it comes in lengths that are commonly attached to pumps. The PTFE liner resists cracking or weakening from some of the most corrosive chemicals, including sulfuric and hydrochloric acid. There’s no need for a gasket because the liner flares out as it passes through the flanges, keeping your line’s contents from touching the fittings. For easy bolt alignment, the flanged ends swivel.
