EISELE engineering heritage and HENN Connector Group integration

EISELE originated in Germany and has cultivated more than fifty years of precision metal machining expertise to produce dependable industrial fluid connections.

Following its integration into the HENN Connector Group, the enterprise established its position as the premier development hub for multi-coupler systems.

The Waiblingen manufacturing plant operates computer numerical control multi-spindle turning centers, optical inspection stations, and fluid pressure test facilities.

All connection assemblies satisfy rigorous international safety benchmarks, guaranteeing leak-free handling of pneumatic air and liquids.

Basicline solid metal push-in fittings and thread adapters

The Basicline portfolio comprises four thousand metal fittings fabricated from resilient nickel-plated brass, engineered for standard pneumatic tubing lines and deep vacuum loops.

The internal collet mechanism retains calibrated polymer tubing without wall deformation up to sixteen bar working pressure.

The selection includes straight fittings, elbow joints, swiveling adapters, tee pieces, and manifolds with metric and imperial threads ranging from M3 to G1/2. Protective electroplating prevents surface oxidation, while nitrile elastomer seals preserve flexibility under ambient thermal fluctuations.

Inoxline stainless steel fittings for aggressive environments

The Inoxline family is machined from high-alloy austenitic stainless steel grade 1.4404 (AISI 316L), designed for pharmaceutical reactors, chemical processing plants, and food packaging machinery.

High surface finish quality along internal fluid channels prevents residue build-up within stagnant internal zones.

Fittings tolerate repeated clean-in-place steam sterilization and aggressive acid or alkaline washing routines, ensuring joint integrity through FKM fluoroelastomer or FFKM seals. Components are deployed in filling machines, biotechnology vessels, and beverage processing systems.

Liquidline fluid couplers for power cooling applications

Liquidline components are engineered specifically for fluid cooling of frequency drives, industrial laser resonators, power electronics, and high-performance motors. Internal flow geometry is optimized through computational fluid dynamics, minimizing pressure drop and eliminating cavitation shocks.

Couplers accommodate deionized water, water-glycol coolant mixtures, and synthetic heat transfer liquids across a wide thermal envelope. Dependable joint integrity shields sensitive electronic circuitry inside drive enclosures from fluid drips.

Multiline 1800 and 1811 modular multi-couplers for swift tooling setup

Multiline multi-coupling plates integrate pneumatic conduits, liquid cooling lines, and electrical sensory wiring within a solitary compact connection module. Implementing 1800 and 1811 multi-couplers reduces tooling changeover duration on robotic arms and press tooling from minutes to seconds.

Series 1800 models offer unrestricted flow, whereas series 1811 includes automatic shut-off valves that eliminate fluid dripping during disengagement. Asymmetric alignment pins prevent incorrect cross-connection of utility lines during manual coupling maneuvers.

Calibrated technical tubing and standardized part number verification

To ensure uninterrupted pneumatic operation, EISELE delivers matched industrial tubing manufactured from polyamide, polyurethane, polyethylene, and fluoropolymers PTFE, FEP, and PFA. Accurate outer diameter tolerances ensure airtight collet engagement without microscopic air leaks.

Accurate part identification relies on the alphanumeric product code marked on the metal fitting body or original packaging. Technical specialists verify thread standards, internal bore diameters, and elastomer compounds, assembling tailored specifications for plant retrofit projects.
