4300 Catalog Pipe Fittings and Port AdaptersMetric ParallelIn Europe, primarily in Germany, the traditional metric parallelthread form is used extensively to connect components inhydraulic systems. This metric thread is designed to thread intoand seal in a female Metric parallel port conforming to ISO-9974-1 (DIN-3852, Part 1). Fittings in this section with malemetric threads use a primary sealing method of an O-ring andretaining ring. Additional sealing methods such as a cuttingface or an EOlastic seal are also available on other fittingswithin the catalog. Sealing is accommodated with one of theaforementioned sealing methods, not with the threads. It isalso important to note that with these male metric threads, theseal occurs on the top face (spotface) of the port, not in an O-ring gland or chamfer as in SAE and ISO-6149 straight threads.A detail of this metric port is shown on page U25.To minimize further proliferation of additional port threadstyles, the International Standards Organization TechnicalCommittee 131 has completed the development of a worldstandard leak-free port connection. It is recommended that thisport, ISO 6149-1, be specified in all new hydraulic fluid powerapplications. Parker and other fluid connector manufacturersare expanding product offering to incorporate the ISO 6149male studs as a standard on many tube fitting products. Parkeroffers the ISO 6149 male stud end, shown in Fig. G7, on severaltube fitting products including: Seal-Lok, EO, EO-2, ConversionAdapters, Plugs, etc. This port, utilizes metric parallelthreads for mechanical holding power and a sealing methodsimilar to the proven SAE Straight Thread O-ring port.
