What makes an empty squeeze bulb work so well?
Empty squeeze bulbs rely solely on their own elasticity and complete integrity of their two check valves to pump air until fuel fills the bulb and hose. Air is compressible and has its own spring rate that tends to minimize the capability of the bulb to pull on its expansion part of the cycle.
What are the problems with squeeze bulbs on boats?
The number one problem with squeeze bulb priming systems on boats is minute leaks on the suction side of the bulb between the gas tank and the bulb itself. Once the main issues with squeeze bulbs are understood, they are relatively easy to troubleshoot and fix.
How does a mercury vapor lamp produce light?
A mercury vapor lamp is a gas-discharge lamp that produces light via an electric arc through vaporized mercury. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. In low-pressure mercury vapor lamps, only the lines at 184 and 253 nanometers (nm) are present.
What causes a squeeze bulb to pull on its expansion cycle?
Air is compressible and has its own spring rate that tends to minimize the capability of the bulb to pull on its expansion part of the cycle. Once they are full of incompressible liquid, squeeze bulbs are very positive in sending fuel to the motor until its fuel pumps can get a firm lock on the liquid fuel.
What kind of light cover is Vaportight lens?
When you need to protect a fixture from inclement conditions, a vaportight lens is your solution. Available in one or two bulb widths and 2′, 4′, 6′ and 8′ lengths. Acrylic: Superb Clarity, Excellent Weatherability, Excellent UV resistance, Good Shock resistance, available in differing D.R. resin blends for improved shock resistance.
What kind of rubber is a bulb seal made of?
Made of EPDM foam rubber, these seals have hollow construction for more compressibility than solid seals. These seals are made of solid EPDM foam rubber. Hollow construction makes these seals more compressible than solid rubber seals. Made of EPDM rubber, they also resist salts.
What kind of cover does a bulb seal need?
A silicone -coated fiberglass cover sheds sparks and molten metal splash. These seals resist steam, most refrigerants, salts, and grease. They can withstand temperatures up to 450° F. A ceramic cover makes these seals more chemical resistant than the seals with a silica cover.
Which is better rubber seal or EPDM bulb?
Able to withstand temperatures up to 500° F, these all-rubber silicone seals resist water and salts. These seals have an EPDM foam rubber bulb. The Buna -N foam rubber bulb on these seals also resists grease, salts, water, steam, and most detergents. The EPDM rubber wiper is firmer and more durable than the EPDM foam rubber wipers.

Is it OK to see lot of air bubbles when I Prime Weedeater?
No fuel reaching chamber. I see lot of air bubble when I prime, prime is pumping fuel but lot of bubbles on return line going back to fuel tank. is it common or I have leak in fuel line ? Share it!

What happens to my Philips Hue light bulbs when I lose power?
Here’s how to automatically reset your Philips Hue smart bulbs with the Power-On Behavior feature. Error! Philips Hue smart bulbs allow for a customized and voice-activated smart home setup. But they will also go back to their original color and brightness after you lose power.
