Liquid Tight Strain Relief - Dome Fitting - Technical Drawing

Features:

This Nylon Strain Relief will provide your application with a product made of exceptional quality.

The self locking ACME thread on the dome top ensures that the overlapping splines apply a concentric seal, thereby preventing the form seal from being pulled out of the fitting & ensuring pull-out protection of your cable without damaging it.

Strain Relief Fittings in all popular thread types and sizes for standard applications in hazardous locations according to EN 50014, EN 50018 and EN 50019:

Machine, apparatus and plant equipment
Measuring control and feedback systems
Control cabinets
Railroad cars and vehicles
Industrial installations
Marine
Off-shore

and in all installations where excellent performance, fire resistance and no twisting or torquing of the cable are critical.

ATEX

ATEX 95 equipment directive 94/9/EC, Equipment and protective systems intended

Appareils destinés à être utilisés en ATmosphères EXplosibles
The regulations apply to all equipment intended for use in explosive atmospheres,
electrical or mechanical, including protective systems. There are two categories of
equipment I for coal mining and II for industrial applications.
Once certified, the equipment is marked by the ‘CE’ (meaning it complies with ATEX
and all other relevant directives) and ‘Ex’ symbol to identify it as approved under the
ATEX directive.
Ex-d = Flameproof
Ex-e = Increased Safety
