[[File:Presse-etoupe.jpg|thumb|An assortment of PG cable glands. Similar glands with DIN/ISO metric threads are also available.]]

The '''Stahlpanzerrohrgewinde''' ({{IPA-de|ˈʃtaːlˌpantsɐʁoːɐ̯.ɡəˌvɪndə|lang}}, "steel conduit thread") standard for [[Engineering:Screw thread|screw thread]]s, more often called by the shortened '''Panzergewinde''' ({{IPA-de|ˈpantsɐɡəˌvɪndə|lang}}), was a [[Technical standard|technical standard]] created in {{wipe|Germany}} and subsequently used in {{wipe|Switzerland}}, Austria, and other neighboring European countries. It has been [[Deprecation|retracted]].  The thread is used to join pieces of [[Engineering:Electrical conduit|electrical conduit]] and cable glands.

Alternative stylings of the German name are ''Stahl-Panzer-Rohr-Gewinde'', an abbreviated form ''StaPa-Rohr-Gewinde'', and the acronym ''PG''.

==Overview==
The standard, codified by the ''Deutsches Institut für Normung'' (DIN, German Institute for Standardization), is DIN 40430. ''Panzergewinde'' sizes are named with the prefix ''PG'' plus a nominal number which approximately corresponds to the maximum cable diameter (in millimeters) that can be passed through the conduit.

Because the walls of the conduit are usually relatively thin, the [[Engineering:Screw thread#Thread depth|thread depth]] is limited. Thus a [[Engineering:Thread angle|thread angle]] of 80° is used. The ''Verband der Elektrotechnik, Elektronik und Informationstechnik'' (VDE) (which began as a [[Organization:Trade association|trade association]] for standardization in electrical engineering) originally standardized (and named) the thread for use with conduit and cable glands that were made of steel, although today the thread is used with both steel (typically [[Physics:Plating|plated]] with combinations of nickel, zinc, or tin to resist rusting) and [[Chemistry:Polyvinyl chloride|polyvinyl chloride]] (PVC).

Beginning in 2000, the VDE standard for cable glands (VDE{{nbsp}}0619) was formally replaced by EN{{nbsp}}50262. After a transitional period of several years during which it could still be used, it was replaced in 2003 by a final metric fine thread with {{convert|1.5|mm|in|4|abbr=on}} [[Engineering:Screw thread#Lead, pitch, and starts|pitch]]. Similarly, conduit threads were replaced by EN{{nbsp}}60423.

Even today, ''Panzergewinde'' cable glands are still often found on [[Chemistry:Chemical reactor|chemical reactor]]s and [[Biology:Bioreactor|bioreactor]]s (for example, PG13.5 thread for screwing in sensors) and various other equipment, enclosures, [[Engineering:Junction box|junction box]]es, and [[Engineering:Electrical connector|connectors]].
