Boss Coupling System
Features: The spud part of the coupling serves as one half
of the connection and is usually fixed to the equipment. The
stem part that is clamped to the hose is the other half. The two
halves are connected or disconnected by rotating the wing nut
onto the spud. When connected they achieve a mechanical,
as well as, a pressure seal.
Services: Boss couplings are all-purpose hose couplings,
universally recommended for steam hose connections. They
are also widely used for air, water, fluid petroleum, chemicals
and liquid petroleum gas up to 1" ID. Boss couplings can be
applied to many types of rubber, synthetic, plastic, metallic
or semi-metallic hose. Consult the factory for specific media
capabilities.
Purpose: Boss couplings supply a convenient threaded fitting
to connect two lengths of hose, or a single length to a male or
female threaded (NPT) outlet.
