WASHER TYPE
|
|
The
leakproof seal in the "Boss" Coupling is affected in the
Ground Joint Style by a soft-to-hard-polymer connection
when the rounded head of the stem is in firm contact with
the beveled polymer insert in the Spud. Job down time to
replace lost or deteriorated washers is eliminated and the
sealing efficiency is not affected by dirt, grime or by
normal wear through repeated use. |
In the washer type coupling, the seal is made by a Klinger
nylon, Nitrile bonded, Kevlar reinforced washer between
wide flat surfaces on the Stem and Spud. A tight
connection is made, without turning the hose by rotating
the Wing Nut and hammering it tight. The washer type is
the original "Boss" coupling, superseded by the "GJ-Boss"
coupling, providing a Ground Joint Seal in place of a
washer type seal. |
PURPOSE:
To supply a
convenient threaded fitting needed to connect two lengths of
hose, or a single length to a male or female threaded (NPT)
outlet on any type of equipment.
The Spud part
of the coupling serves as one half of the connection and is
usually fixed permanently to the equipment. The Stem and Nut
attached (clamped) to the hose is the other half. The two
halves are connected or disconnected by rotating the Wing Nut
on the Spud, to achieve a mechanical as well as a pressure
seal.
SERVICES:
All-Purpose
Hose Couplings, universally recommended for steam hose
connections. They are also widely used with equal efficiency
for high or low pressure Air, Water, Liquid Petroleum Gas,
Fluid Petroleum Products, Chemicals, Potable Fluids and almost
any other type of fluid or gas. They can be applied to all
types of rubber, synthetic, plastic, metallic (with special
stems) or semi-metallic hose. Consult Factory for specific
media capabilities.

"EZ-Boss" Ground Joint Fittings

In addition to the above mentioned
features of Dixon Ground Joint fittings, the "EZ-Boss"
non-metallic polymer seat is not subject to corrosion and
offers resistance to chemicals and steam found in
manufacturing facilities. A precisely machined recess holds
the seat firmly in place, allowing it to absorb harsh
punishment. Recommended for steam service up to 450°F. Easy
to seal and works with existing "Boss" Ground Joint Stems. |
