V10 Starter Hose Instructions
Starter hoses include female quick-disconnect coupler crimped on one end and V13
hose-to-pipe (3/8” NPT) adapter.
1. If the air source has a threaded attachment, use the supplied V13 hose-to-pipe
(3/8” NPT) adapter to connect the threaded female fitting on the hose to the air
source.
2. If the air source has a coupling attachment, refer to matching QD nipple specifica-
tion and use either a V12 (1/4”) or V13 (3/8”) to connect the nipple to the hose
(nipple and adapter may be included with certain part numbers). Attach QD nipple
to QD coupling on the air source.
3. Connect the respirator’s breathing tube fitting to the female quick-disconnect cou-
pler on the V10 hose.
NOTE:
Threaded seal tape should be used on all threaded attachments. Beveled end of
adapters are for hose side of connections.
V10 Extension Hose Instructions
Extension hoses allow you to add Bullard breathing air supply hose to your Bullard
respirator’s starter hose or another length of extension hose. For more information
on maximum permissible hose lengths, configurations and necessary air pressure
operating ranges, please refer to the User Manual Breathing Air Pressure Table.
Extension hoses include V11 hose-to-hose adapter and V13 hose-to-pipe (3/8” NPT)
adapter.
1. Remove any quick-disconnect nipple or adapter from the air source end of the
starter hose and replace it with the V11 hose-to-hose adapter.
2. Connect one end of extension hose to the open end of the V11 adapter just inserted
in the starter hose.
3. If the air source has a threaded attachment, use the supplied V13 hose-to-pipe
(3/8” NPT) adapter to connect the threaded female fitting on the hose to the air
source.
4. If the air source has a coupling attachment, refer to matching QD nipple specifica-
tion and use either a V12 (1/4”) or V13 (3/8”) to connect the nipple to the hose.
Attach QD nipple to QD coupling on the air source.
NOTE:
Threaded seal tape should be used on all threaded attachments. Beveled end of
adapters are for hose side of connections.
Respirable Breathing Air
Respirable breathing air must be supplied to the point-of-attachment of the approved
breathing air supply hose. Government regulations require that all breathing air
meet the specifications for Grade D breathing air as described in Compressed Gas
Association Commodity Specification G-7.1-1989 and specified by federal Law 30 CFR,
Part II, Subpart J, 11.121(b).
Point-of-attachment
Air pressure at the point-of-attachment must be regulated with the ranges specified
on your respirator’s MSHA/NIOSH approval label.
NOTE
:
You can repeat the extension hose connection steps using Bullard V10 hoses.
However, do not exceed the lengths specified on the approval label or in the
instruction manual for your specific respirator.
DO NOT connect your Bullard breathing air supply hose to nitrogen, toxic gases,
inert gases, or other non-breathable, non-grade D air sources. Breathing air hose
connection fittings must be incompatible with fittings for other industrial gases as
described by the Compressed Gas Association.
