5mm / division	JB Weld Steel Epoxy Surfaces sanded and degreased	Coil wound on tube, then twisted for extra clearance. Better breathing

1/8" -27 NPT pipe tap is used to clean out threads after epoxy hardens.
Tap can also be used to "adjust" nut thread depth for proper tightness onto MNPT (tapered) fittings.
Use tap sparingly, enlarge nut threads only enough to compress O-Ring to "finger tightness".
Please treat these instructions as "general suggested guidelines" only.

BM9043-01 BOM
for Vac Filter using 1/8" NPT Bulkheads

	FoodSaver® Vacuum pump access Tubes
Extra tubes for external Filter.	All Internal tubing replaced with 1/4" OD PVC Note added 3/16" Barb Tee.	To pinch tubing: Heat then squeeze with pliers.
Connecting both tubes with 3/16" barb gives normal operation. No filter or gauge. Grommets not shown.	Both  tubes to external filter. Normal operation, but with filter and vacuum gauge. Vacuum pump is protected.	Chamber is bypassed. Pressing "ON" button will never activate seal heater or reach automatic cutoff. User must deactivate "ON" button when optimum vacuum is attained.
		My Preferred configuration  for vacuum sealing jars. On this model, does not turn on heater needlessly or use drip tray seals. Pulls better vacuum. Jar Sealer filter keeps particles out of tubes and both are easy to clean and cheap to rebuild.

	Magic O-Ring !!
FoodSaver® Wide Mouth Jar Sealers work well on almost all jars I have. However, I have one type of jar which will not form a vacuum. Rarely, I read online of others having "sealing problems" with the Wide Mouth Jar Sealers.
		My problem jars have a glass 1" rings which are a bit smaller in OD than those which do seal. A #151 Silicon O-Ring makes up the difference in OD. Sometimes, a bit of "fiddling" is necessary until they "catch"

This O-Ring also "fixes" an older vintage model Wide Mouth Jar Sealer i got at a yard sale... Good Price. (More info for another video perhaps) Without the O-Ring, it seals very few wide jar types.  With it, almost all?.

	Accessory Hose for Jar Sealer Airline Tubing and detail
		Standard Airline Tubing Measured: 5.6 mm (.220") OD  x 3.6 mm (.144") ID Fits into Foodsaver® Jar Sealer Port (and other accessories?). Needs a bit of stiffening and an insertion "stop point". Thus the 1/8" Nylon Barb.
DIY replacement Foodsaver® accessory port hose using Airline Tubing (Jar Sealer side)	Airline Tubing fits 3/16" Brass and Nylon barbs
		Vacuum pulls the Tubing / Barb assembly tighter into the Jar Sealer Port.   Forms a nice tight fit. Soft plastic tube parts prevent damage to plastic accessory port holes.
Push barb into hose as shown. Use flat end of drill bit or equiv.	Airline Tubing & 1/8" Nylon Barb .	Note: Tubing can be clamped onto barb using a twist tie or similar. (clamp not shown)
