Knowing How Tight to Attach Hose Fittings
Attaching hose fittings is a skill that every homeowner has to master because one will be doing a lot of that in a lot of home improvement projects. But what puzzles most of us is how tight is tight when it comes to attaching hose fittings?
Of course, you’ll have to twist until you cannot possible turn the fitting anymore. But the basic rule is that as long as nothing drips from the fitting, you’re good to go. But know there’s another question that comes up. Is there any special kind of device that must be attached to the hose and fitting to ensure a snug fit? Hose clamps or hose clips are devices that are attached to both your hose and fitting to prevent any bursting brought about by the pressure of the substance that’s coursing through the hose.
Screw clamps are usually stainless steel bands that have screw thread patterns impressed on it. You wrap the band around the hose. Place the end of the band through the small gap between the band and the captive screw which is positioned on the other end of the band. When you tighten the captive screw, it tightens the band around the hose and keeps the hose from being pulled away from each other.
Screw clamps are often used in hoses with a diameter of 1/2 inches and below.
From what the name suggests, spring clamps are made from spring steel. The clamp is designed in a way that there are three protrusions all in all. The entire width of the clamp is divided into 3 sections. The 2 protrusions are found on the sides. The last protrusion is at the middle of the pipe, just a few inches away from the 2 other protrusions. Although all 3 are protruding upwards, the 2 protrusions were cut in the opposite direction of the middle protrusion.
When attaching the spring clamp, one must push the protrusions closer to each other in order to expand the circumference of the spring clamp. Once it has expanded, you can slide the clamp into the hose and into the barb. Once you have the spring clamp where you need it to be, you can release the spring clamp to compress the clamp back into a narrower diameter to keep the hoses together.
Because of its ability to expand if enough force is exerted to it, spring clamps aren’t often used on hoses that are highly pressurized.
Wire clamps look like wires that are formed into a U-shape. One end has a captive nut while the other end has a captive screw to it. When you attach the nut and the screw together and you tighten it, the ends will bend outwards and the wires will start overlapping each other so that the clamp becomes completely round.
