About Stopper

Stoppers push into an existing fitting and close an unused port pressure tight. They save rebuilding the line when a take-off point is taken out of service for the time being, or when a section is blanked off for testing. The group covers tube outside diameters from 4 to 28 mm.

What matters when choosing

• Tube O.D.: 4 to 28 mm. The stopper carries the stem diameter of the tube that would otherwise sit in that port.
• Max. working pressure: 16 bar on the small sizes, with 10 bar quoted from 10 mm stem diameter upwards.
• Min. working pressure: -0.95 bar, so a port in a vacuum section stays closed as well.
• Colour: the small stoppers are red, from 15 mm they are black. That makes them easier to spot in an installed run.
• Material: acetal copolymer (POM) throughout, from the speedfit range and matching its push-in fittings.

Typical applications

• Taking single ports on a manifold out of service
• Pressure testing a newly installed line
• Spare ports in drinking water and process water installations
• Temporary blanking during machine conversions
• Keeping dirt out of open fittings during installation

All stoppers are made of acetal copolymer (POM) and carry drinking water approvals DVGW, KTW, FDA and NSF. The country of production is the United Kingdom.
