To clamp those smaller pipes, simply open the 1-inch jaws and slip the necessary-size clamping jaws inside.
Clamping tools are often one-size-fits-all. They slide over the knob on the clamp and squeeze it, and those knobs are relatively universal in size. These gauges have U-shaped cutouts meant for specific pipe sizes.
To use a go-no-go gauge, slide it over the joint. Check it from several angles. The gauge should slip over the crimp about halfway before stopping.
If it slides all the way over the crimp, or not at all, the joint may have problems when pressurized. Over time, clamping and crimping tools can fall out of perfect calibration.
Applying pressure many times over the course of a plumbing project can stretch the jaws a bit, in which case dial them back in. Most of the best PEX crimp and clamp tools have calibration gauges and adjustment screws, and they often come with the wrenches required to adjust them. Use these gauges to determine how far out of calibration the tool is, and tighten it back to the ideal setting.
Many of these tools have adjustments on both jaws, allowing for calibrating to a perfectly round result. The gauge can also determine if the jaws are overtightened, which can just as easily lead to a leak. Many of the best PEX clamp tools have removal functions for separating clamps from the pipe. However, the fitting underneath should be completely intact. To remove a clamp, switch the clamping tool to the cutting function.
Then remove the clamp. Nothing hurts the bottom line more. Imagine having an already small margin in order to win a project, only to have that margin eaten up by your first callback.
You might not even have to imagine it; you may be routinely experiencing it. Understand that all PEX has some degree of thermal elastic memory.
This is important when comparing how the connections function over time. The process for making a connection on a square-cut, clean pipe is as follows. This inevitably leads to a higher occurrence of dry fits; i. Another concern is that because these parts are relatively easy to purchase at a variety of retailers, it means any untrained individual can purchase and install these types of fittings. Push-to-connect fittings conform to the ASSE standard. This process involves sliding a ribbed fitting into the PEX tube and crimping a seal ring around the connection point.
These rings are typically made of copper, but may be found in plastic as well as brass. The inner edge of the ring is lined with teeth which firmly seal the PEX tube around the fitting.
A special sized crimping tool is required for such an installation. All of these materials are very common and can be found at a local hardware supply store. Another common connection method is a "Cinch" ring. This is very similar to the crimp method in that a metal ring is used to seal the PEX tube against the fitting.
Which one is ideal for your project? Read on to find out how they work and their differences. Usually, there are two main methods of connections in PEX installation; the crimp method and the cinching method. Others also include press or push connection, which eliminates the use of any tool whatsoever. Although users find it fast and easy, it leaves a wide margin for error. Another method is the expansion technique. It is considered very reliable but quite pricey to install. It is the oldest and most popular method of sealing connections.
Both professionals are homeowners trust PEX crimping tools to provide fast, reliable, and accurate seals. PEX crimp tools typically feature copper rings for proper tightening. Besides, the teeth inside the ring firmly seal the PEX tubing. This sealing method is similar to the crimping technique in that it uses a metal ring to make a connection. But instead of copper, it uses a stainless steel ring.
Moreover, with PEX cinches or clamp tools, you only tighten a specific spot on the ring rather than the whole body. The cinch method is much cheaper because it eliminates the need to acquire tools of varying sizes.
