Flexible Hoses

Flexible HosesFlexible hoses are used to transfer compressed and liquefied gases. They are available in various lengths, in either all stainless steel construction or stainless steel lined with PTFE.

The SG6450 Series, all stainless steel hoses feature a double overbraid and have end fittings Heliarc welded to both the corrugated liner and the overbraid. The SG6460 Series, PTFE lined versions have a single stainless steel overbraid with end fittings that are swaged to the liner and overbraid.

For applications which require constant handling and flexing, our SG6450-A Series with armor casing provides protection from kinking, braid abrasion or stress at the ends. Also,the armor casing provides an added measure of protection for operators, exhibiting a smooth surface for handling and the capability to support a 600 lb. load under tension.

Note: The SG6460 Series Stainless Steel Flexible hoses lined with PTFE are not recommended for Oxygen service. Refer to CGA E-9, 1998 Standard for additional information.
