Triple-Lok® 37° Flare Tube Fittings
4300 Catalog
International Acceptance
The Triple-Lok male flare end is attachable to either inch tube,
metric tube or a hose assembly. Parker offers many different
port thread options for the various international hydraulic ports
available. This is one of the primary reasons for its worldwide
acceptance.Parker has traditionally offered a “MetricTriple-Lok”
product line directed at the Metric, ISO-6149 and BSPP port us-
ers. Rather than carrying a separate catalog section, this range
of international fittings has been integrated into the traditional
“Triple-Lok” section.
To illustrate the versatility of Triple-Lok, refer to Fig. C3. A single
37° fitting body will accept both inch and metric tube sizes by
simply changing the sleeve. Thus, a dedicated line of sleeves
is offered for inch and metric tube. The universal tube nut and
fitting body is used with either inch or metric tube, thus saving
on component costs and making the Triple-Lok fitting more
versatile. Also, the 37° body without the nut and sleeve is very
popular as a hose adapter.
Study the following example illustrating the options with an SAE
–8 (1/2”) Triple-Lok fitting:
1. Fitting with a –8 (1/2”) sleeve and –8 (1/2”) tube nut can
connect to a 1/2” o.d. flared tube.
2. Fitting with a 12 mm sleeve and –8 (1/2”) tube nut can
connect to 12 mm o.d. flared tube
3. Fitting without a nut and sleeve can be used as a 1/2” hose
adapter when connected to a hose swivel.
Table C2 illustrates an even clearer picture of the flexibility of
the Triple-Lok 37° system. It shows every “convertible sleeve”
connection for the 37° flare design. For example, if 25 mm tube
is being used, a –16 (1”) 37° flare fitting together with a 25 mm
(TXS25) sleeve and a standard –16 (1”) flare fitting nut would
be all the necessary components to connect and seal a 25 mm
flared tube assembly.
Tube Wall Thickness – Inch and Metric
Minimum/Maximum tube wall thickness is based on the pres-
sure holding capacity of the fittings and subject to maximum
wall thickness limitations.
