Blue-Max® Boiler Gaskets
BOILER GASKETS
We are the
sole Australian agents for the famous "BLUE-MAX"® Boiler Gaskets.
These unique high quality gaskets are made from a proprietary tacky glass cloth, synthetic
fibres and brass wire mesh reinforcing, with a coating of P.T.F.E. material to MIL SPEC
T-27730A. The gaskets are easily installed, and deliver trouble free service. When the
time comes for routine maintenance, they are easily removed because of the P.T.F.E.
coating. Gaskets are available in all sizes both manhole and handhole.
Queensland Gaskets has been providing
boiler gaskets to the industrial boiler servicing industry for a number of years. Queensland Gaskets
carries the full range of Blue Max boiler
gaskets in the manhole and handhole oval shapes, which are available for immediate
delivery to all boiler servicing companies around Australia.
The unique feature of the Blue Max
boiler gasket, is that it is wrapped with a fine Teflon coating to prevent the gasket from sticking to the plate when it comes
time to service the boiler. The Blue Max boiler gasket is constructed of a folded proprietary tacky blue plastic material
which is reinforced with a fine copper wire
mesh to ensure that the gasket retains
strength under strict temperature and pressure environments. Queensland Gaskets managing
director Guy Quarterman commented that, ‘The Blue Max
boiler gasket range has been a true success and our customers are delighted with the
quality and longevity of the product’.

Installation Instructions
- Remove old gasket and thoroughly
clean cover plate flange, ring, or shell gasket surfaces.
- Position Blue-Max® gasket on cover plate. Please make sure the
gasket is pushed down tight and flat around shoulder. Note: If shoulder of plate is
rounded making the gasket hard to keep in place, use Blue-Max®
Sta-Ons®. (Do not use any grease, sealant, or
lubricants.) This will ensure that one side of the gasket does not slide back up onto
the shoulder during installation causing only the inner edge of the ring or shell to catch
only the outer edge of the gasket causing premature failure when pressure builds.
- Install cover plate into opening,
set crab/s, tighten nut/s finger tight while making sure the inside diameter of the gasket
is centred evenly on the inside edge of the ring or shell.
Note: If the cover plate is too small for the opening in the boiler, it's easy to
place the cover off centre. An off centre plate will cause the same occurrence as
previously described in the above note (2).
- Tighten nut/s with wrench a full
turn. When all gaskets are in place as previously described, torque style #810-T hand hole
gasket sizes to 90-ft. lbs., and style #800-T manhole gasket sizes to 120-ft. lbs.
Note: All plates with double crabs should be alternately tightened ( ie).: 40 / 80 / 120-ft. lbs.
- Fill and fire boiler. Note: Should
gaskets leak while filling boiler do not tighten nut/s. The soft rubber compound under the
PTFE cures up with heat allowing the rubber to fill into the pits and irregular sealing
surfaces. During this curing process it is not uncommon for leakage to occur.
- Once the boiler has come up to
operating temperature and pressure, allow the boiler to operate for four hours. After this
period, retighten any leaking gaskets only enough to stop leakage.
- Extra care should be taken when
installing gaskets on the bottom of a boiler shell. Small particles of scale or sand tend
to run down on the mating surface between the time the surface is cleaned and the cover
plate is put in place ready to be torqued.
- Blue-Max® boiler
gaskets are sold and intended for use on steam boilers.
Performance data for the Blue-Max® boiler gaskets have been developed from
field-testing, customer field reports and or in-house testing. While the utmost care has
been used in compiling this information, we can assume no responsibility for errors.
