Elster 71190103GN Fitting SVHD 1-1 4x1CTS-090 090 102X1

Elster 71190103GN Servi‑Sert SVHD fitting is a service-head adapter (SVHD) from Elster Perfection designed to make a secure polyethylene‑to‑metal transition in gas distribution systems. As part of the Servi‑Sert SVHD family, this model encodes multiple size options in its designation (noted here as SVHD with 1‑1 4x1CTS‑090 090 102X1), reflecting compatibility with common PE‑CTS and CTS‑based configurations used in residential and light commercial installations. Built for quick, leak‑tight installation, the SVHD fittings are designed to minimize loose parts during assembly and to resist pull‑out under typical service pressures. The PN 71190103GN designation identifies this exact configuration within Elster’s catalog, with a GN suffix consistent with other Elster Perfection items that are sold under the same branding and product line. Typical applications include natural gas service drops and LP gas distribution networks where a durable, field‑reliable head connection is required for polyethylene service lines, enabling fast commissioning and service restoration without compromising safety or code compliance.
