Product catalog summary
Introduction
Aflex Hose has developed a range of PTFE encapsulated end fittings in response to customer requests. These fittings serve as an alternative to standard non-lined fittings, offering a PTFE lined option without the need for assembly and flaring. While they do not provide the full bore size and entrapment-free design of integral lined fittings, they are easier to assemble and have a larger bore than conventional PFA encapsulated fittings.

Construction and Application
Encap fittings are assembled using the same ferrules and procedures as non-lined fittings across the Aflex PTFE hose range. The PTFE encapsulation is available in natural or antistatic PTFE, with wall thicknesses of 1.5mm for sizes up to 1.5 inches and 1.8mm for sizes 2 inches and above. It is important to use only Aflex Hose components to avoid liability for failures.

Codes and Availability
Encap fittings are available in various designs, with some requiring special orders. Certain fittings are lined with a machined PTFE liner, while others use a flared PTFE tube for sealing. Some fittings are only available as specials, made to order.

Performance Testing
Encap fittings have undergone rigorous testing, including burst pressure, helium diffusion, and continuous flex testing. These tests confirm that Encap fittings perform comparably to standard non-lined fittings.

Properties
The temperature, pressure, and other properties of Encap fittings align with those of the relevant hose and non-lined fittings as detailed in Aflex Hose product brochures.

Dimensions and Part Numbers
The document provides detailed dimensions and part numbers for various fitting types, including swivelling flange spigots and cam & groove fittings. Specific part numbers are listed for different sizes and configurations.

Encap Data Sheet-1

Revision Date PTFE ENCAPSULATED (ENCAP) END FITTINGS Loose BSPP Fixed Male Encap Fitting and a standard, non-lined Ferrule Swivel Flange Encap Fitting Crimped on to Corroline+ Hose Introduction In response to requests from Customers who self-assemble Aflex Hose products, Aflex have developed a basic range of PTFE encapsulated end fittings. These can be used in place of standard non-lined end fittings to provide a PTFE lined alternative, without the need to assemble and flare an Integral PTFE Lined end fitting. Encap fittings do not provide the same advantages as Integral Lined fittings, namely the full hose bore size through the fitting, and no internal entrapment areas. Encap fittings do, however, provide a fully PTFE lined fitting with a flared face which is easier to assemble. Also, the Aflex Encap fitting design has a significantly larger bore than the conventional PFA encapsulated fittings available from other suppliers. Construction and Application Encap Fittings are assembled and crimped using the same non-lined ferrules, crimp diameters and assembly procedures that are used with standard non-lined fittings, on all the Aflex PTFE hose product range. Note: Corroline+ hose can be supplied with an alternative Direct Crimp (DC) fitting design, which is also available in the Encap version, to special order. The PTFE encapsulation is either natural or antistatic PTFE as required, with a PTFE wall thickness of 1.5mm (0.060”) for sizes up to 11/2”, and 1.8mm (0.070”) for sizes 2” and above. Important Note: The use of Encap fittings with hoses, ferrules or other components which are not all supplied by Aflex Hose is strictly prohibited, and no liability will be accepted for any failures which result from such abuse.
