Coupler Assembly Instructions
Standard assemblies for both the Spectrum-PD and
Spectrum-PDE come with a CA30 (Industrial Interchange)
coupler assembly. The nipple is assembled onto the second
stage regulator hose on the Spectrum-PD (See Figure 1),
and onto the first stage regulator hose on the Spectrum-
PDE (See Figure 2). The female coupler is snapped onto
the nipple for shipment.

To assemble a different coupler assembly
on the respirator, follow these steps:
•Remove the Industrial Interchange nip-
ple from the first or second stage regu-
lator, using a wrench to loosen the con-
nection.
•Before connecting the other nipple,
ensure that the in-line screen and white
retaining ring are still in place inside the
female threaded fitting. Be sure to re-
install the metal tab (See Figure 3).
•Apply thread sealant on threads of new
nipple and tighten with a wrench until
wrench-tight and leak-free.
(Bullard recommends using
Loctite 242 sealant.)
• To attach the female quick-
disconnect coupler to the air-
line hose, screw the coupler
onto the airline hose, using
the adaptor that is attached to
the coupler (See Figure 4).
Thread sealant is not neces-
sary at this connection.

WARNING : Use only Spectrum Pressure Demand components
and replacement parts manufactured by Bullard and approved by NIOSH
for use with this respirator. Failure to use components and replacement
parts approved by NIOSH for use with this respirator voids NIOSH
approval of the entire respirator, invalidates all Bullard warranties, and
may cause death, lung disease or exposure to other hazardous or life-
threatening conditions.
DO NOT connect the respirator’s air supply hose to nitrogen, oxygen,
toxic or inert gases. Failure to connect to the proper air source may result
in serious injury or death. Be certain your employer has determined that
the breathing air source provides at least Grade D breathable air.
