4 Apeks Regulator Service and Repair Manual
● All chrome plated parts - Inspect for any excessive cor-
rosion indicating weak or absent chrome plating. Also look
for any signs of peeling or flaking of the chrome plating.
● Regulator pre-test - A regulator pre-test should include
all tests outlined in the test section for each regulator. A
pre-test will assist the technician in determining if there are
any specific performance deficiencies not mentioned by the
customer.
INFREQUENTLY USED REGULATORS
Do not assume that the regulator is in good condition be-
cause of infrequent use or because it has been in storage.
Deterioration of the O-rings and corrosion can still occur
under these circumstances.
WORK AREA & REQUIRED TOOLS
Servicing and repair of the regulator should be carried out
in a clean well lighted work area. As each regulator is dis-
assembled all parts should be kept separate from parts of
other regulators. Some special tools are required for proper
disassembly and reassembly. Please see Table 1 (page 5)
for a list of these tools.
O-RING REMOVAL
When removing O-rings, care must be taken to not damage
the regulator surfaces in contact with the O-rings. Tools
used to remove O-rings must not have any sharp edges or
points that could scratch metal sealing surfaces. Sea Quest
strongly recommends that all O-ring removal tools should
be made of either brass or plastic.
LUBRICATION
O-rings should be lubricated with an approved compound
(please refer to Table 2 for proper lubricants). O-rings should
be lubricated only with a very light film of grease. Do not
use spray (aerosol) lubricants under any circumstances. The
aerosol propellant may damage the plastic and rubber com-
ponents of the regulator, and the lubricant will quickly
evaporate, providing little or no lasting benefit.
Do not use any petroleum based lubricants or products,
or any aerosol sprays to lubricate or clean any part or
component of Apeks regulators. The petroleum base
or propellant gas may attack or weaken the plastic or
rubber parts. Refer to Table 2 for approved lubricants.
Apeks regulators are intended for use in water tempera-
tures warmer than 45ºF (7ºC). Colder water may cause
regulators to be more sensitive to a freeflow condition
and can lead to a situation that requires an appropriate
response to prevent serious injury or death. Users of
Sea Quest regulators are advised to ensure that they are
adequately trained to deal with a regulator in a freeflow
condition or an out-of-air emergency before attempting
to dive in a cold water environment.
