Straub Eco Grip Pipe Connectors
Economical - for use in lower temperature and pressure ranges.
The axial restraint STRAUB ECO GRIP is designed for use on metal pipes at low temperatures and pressures (up to 6 Bar). As a result of its innovative, patented design it makes connecting plain-ended pipes even more economical, yet it can still correct:
This ready-to-use coupling is removable and reusable, and due to its slim casing, even more space saving.
STRAUB ECO GRIP is ideal for use where the requirements of the pipe system are low and appearance is also an important consideration, for example:

Straub Plast / Combi Grip Pipe Connectors
Straub Plast Grip STRAUB PLAST GRIP ø 40.0 - 160.0 mmAxial restraint pipe coupling for plain-ended plastic pipes. Used in the gas and water supply industries as well as in industrial pipe line construction. For vacuum or pressure pipes, for thick-walled PE pipes (require stiffening rings) as well as thin-walled PVC pipes. The STRAUB PLAST GRIP is the ideal way of connecting plastic pipes. Example of an application - Potable Water Processing, Local Community of Saviese, Switzerland: Supply line connected with STRAUB PLAST GRIP 110 mm. Straub Combi Grip STRAUB COMBI GRIP ø 40.0 - 160.0 mmPractical - for transitions. The STRAUB-COMBI-GRIP ensures a perfect connection at transitions between plastic and metal pipes. The advanced technology and high-specification manufacture ensure increased safety and reliability wherever this coupling is used. Joins plain-ended plastic and metal pipes and compensates for differing outside diameters. Non-weathering and no pipe-end machining required. Note PE pipes require stiffening rings. Fire safety system for alcohol tank farm in Switzerland - Fire-fighting water pipes with transitions from stainless steel to plastic (PE). |

Straub Open-Flex Pipe Connectors
The Straub Open-Flex is a range of hinged, non-axial-restraint, pipe couplings for pipes of all materials.
The Straub OPEN-FLEX is available in a number of different versions: hinged, one-piece or two-piece casing.
The specifications and properties are the same as for the STRAUB-FLEX with slightly reduced working pressure.
The great advantage of STRAUB OPEN-FLEX is that it can be fitted to existing pipes in situ, without any need to remove and re-lay the pipes.
This makes it the ideal solution for permanent repairs of pipe joints, cracks, etc. Simple and reliable.

Straub Fire Fence Pipe Connectors
STRAUB FIRE-FENCE
The fire resistant coupling for use wherever fire protection is required by law.
The STRAUB FIRE-FENCE combines functional design with latest technologies.
The pipe coupling is based on the reliable and well proven STRAUB coupling system and fulfils IMO (International Maritime Organisation) and IACS (International Association of Classification Societies) requirements alike, which have been in force since 1.1.2007.
Even with its flame protection, the coupling is space-saving, shows significantly improved crush resistance and, thanks to the innovative design, is also lighter than its predecessor or any comparable competitor's product.
In the event of a fire, the intumescent fire protection coating expands, protectively enclosing the coupling. During this process, the coupling retains its full operational capability - without any limitations
