Glass Hydrometer barrel

Does anyone here have a source for a replacement GLASS tube ( body) for a squeeze bulb type battery hydrometer?
dimensions of glass tube are approximately:
diameter... 22.5 mm = 7/8 inch
Length.....150 mm = 6 inches
probably should buy TWO , so I have a spare.
Thank you.

    Dean,

    I do not recognize the dimensions vs any specific manufacturer.

    It is reported that Freas (sp?) has supported some customers directly with some parts in some cases for things that have not worked too well for their customers.

    Unfortunately, the sponsor of this site, N AZ W&S no longer carries Freas. And the brand that they do carry, Brady, causes concerns to me, as the red Silicone-like rubber parts turn BLACK in a matter of weeks of use. Am concerned about contanimation of valuable battery banks.

    In the past, when I broke the glass float, just bought a new Hydrometer. You are in AK, so this may be more difficult for you. Good Luck, Vic

    If the float is still OK, it does not care what the barrel is, even if it comes from the cooking isle of the grocery store.. It just has to float

    Yep. I was thinking of the clear, polycarbonate basters, not the milky ones.

    Oldie but goody post from August of 2010:

    Blue Board vs fumes:

    Here is one thread were I posted the acid resistance of various materials. Scroll down a couple posts.
    I would start by identifying the type of plastic (perhaps, the recycle symbol with the number inside--typically 1-7).
    Let’s start with #1 PET which stands for Polyethylene terephthalate. Soda bottles as well as some beer and liquor bottles are made from PET along with a variety of other food bottles and trays. PET can be melted and drawn out into long fibers and recycled into carpets, fiberfill for jackets, and fabric for T-shirts and shopping bags which unfortunately cannot be recycled. Manufacturers want recycled PET and buy it. Coca Cola has finally started using a measly 3 percent recycled PET in their bottles. Be aware that local recyclers only accept narrow-neck PET bottles. I have surmised over the years that used PET food containers with sticky food scraps contaminate the recycling machines.

    Milk and water jugs are made from number #2 HDPE or high-density polyethylene. Clear HDPE could easily be made into new containers. The colored HDPE (liquid detergent, and shampoo bottles) is generally recycled in plastic lumber. Those tough Tyvek mailing envelopes and white contamination suits are also a form of HDPE and are impossible to recycle.

    Vinyl or polyvinyl chloride (# 3 V) could be recycled. It is used for clear food packaging and plumbing pipe. However, collecting it for recycling is cost-prohibitive because there are not enough items made from the material to warrant local factories to recycle it into new products. They are generally used once and tossed.

    Low-density polyethylene (# 4 LDPE) is very flexible and made into bags for bread, frozen food, and grocery. Some of these bags are recycled into new bags or plastic lumber such as Trex. This plastic is lightweight and trucking it back for recycling uses more energy than producing a virgin product. Unless there is a recycling factory close by, most LDPE ends up in the landfill. Consider using cloth shopping bags. My husband and I have used the same bags for over eleven years.

    Polypropylene (# 5 PP) is made into yogurt, margarine, and other food containers. Like number 3 V, there are not enough containers made from PP to justify collecting it and shipping it to a recycling factory. In places where big industries use PP, there is enough volume for it to be sold for recycling.

    Then there’s #6 PS - Polystyrene, the plastic that I would ban from the face of the earth. Solid PS is made into compact disc jackets, eating utensils, and take-out food containers. The expanded PS know as Styrofoam is used for packing materials, coffee cups, meat trays, and egg cartons. The cost of moving used Styrofoam is higher than making it from virgin oil. Jax Place reported, “Foam recycling is a scam to make you feel OK about buying it. Don’t buy it; PS is buried in landfills.” Styrofoam is always found in our local creeks and rivers where birds and fish think it is food clogging up their digestive tracks thus ending their lives.

    The last of the labeled plastics is #7 OTHER. I echo Mr. Place’s voice, “Don’t buy this stuff unless you want to keep it. It can’t be sold or recycled.” Catsup bottles have wavered between PET and OTHER over the last few years. Lids and imported containers are likely to be made from mixed resins known as OTHER.
    Then use a Chemical Resistance Data Base like this one.
