Description
Claws for DN 160 - DN 250 ISO-K with long bolts M10 × 35 are fastening components for larger ISO-K vacuum flange joints covering the DN 160 to DN 250 range. Designed to work with the stated long bolts, the claws provide the clamping interface needed to hold mating ISO-K flanges securely during assembly, maintenance or retrofit of laboratory and process vacuum systems. The M10 × 35 bolt specification indicates the thread diameter and length associated with this claw set, consistent with hardware commonly used on bigger ISO-K connections. Offered as a one-piece pack from manufacturer WELCH, the product sits in the accessories and spare-parts segment for laboratory equipment and supports correct flange alignment and load distribution at the joint. Size coding DN 160 - DN 250 together with the M10 × 35 bolt call-out allows straightforward matching to existing drawings, bill-of-materials entries and service kits. These claws are appropriate wherever ISO-K claw-and-bolt fastening is specified instead of other clamp formats on DN 160–DN 250 vacuum lines and related laboratory apparatus.

Questions about Claws for DN 160 - DN 250 ISO-K with Long Bolts, M10 x 35
What is this article?
Claws for DN 160 - DN 250 ISO-K with Long Bolts, M10 x 35 is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
