Description
Hose barbs for 5/8" hose to NPT 3/4" internal thread provide a dedicated connection set for laboratory recirculating chillers. Each pack contains two hose barbs that adapt a 5/8 inch hose to an internal NPT 3/4 inch port and are specified as suitable for all SmiChill recirculating chillers. The fittings create a defined transition between flexible tubing and the threaded ports used on temperature-control equipment, supporting orderly assembly of cooling circuits. With a net weight of 0,150 kg, the set remains compact for bench and system installation work. These components from manufacturer Julabo help configure fluid paths when hose lines must join NPT female connections on chillers. Laboratory users select such barbs when building or modifying cooling loops that require dimensional match between hose diameter and thread standard. The two-piece format covers typical supply and return lines in recirculating cooler setups. Within general laboratory materials applications, the hose barbs supply the mechanical interface needed to integrate SmiChill units with 5/8 inch hose systems in a straightforward, repeatable manner.

Questions about 2 Barbed fittings for tubing 5/8'' inner dia. to NPT 3/4'' female
What is this article?
2 Barbed fittings for tubing 5/8'' inner dia. to NPT 3/4'' female is the article on this page. Luminix Health distributes Julabo 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.
