A female thread is an internal thread.

A taper thread (commonly BSPT – British Standard Pipe Taper thread) has a diameter which increases or decreases along the length of the thread and is denoted by the letter R.

R, Rp & Rc are the same as BSPT (tapered thread). BSPT threads are always conical if it is male thread (R), but a female thread can both be conical (Rc) and parallel (Rp).

G threads are taken from BS EN ISO 228-2:2003 pipe threads where pressure-tight joints are not made on the threads. The pressure tight joint is achieved by the compression of a soft material (such as an o-ring seal or washer) between the end face of the male thread and a socket or nipple face, with a tightening of a back nut.

G is the same as BSPP (parallel thread). BSPP threads are parallel, both male and female (G).

High purity nitrogen has been used for decades in Nascar, Formula One, the Tour de France, the US Military, and many other applications where safety, speed and economy are vital – so you would think the answer would be yes.

However, it’s accurate tyre pressure which makes the difference, and nitrogen can help maintain this for longer periods of time.

Nitrogen does offer an advantage of its own over air. Air includes a small percentage of water which will corrode your wheels once it’s inside your tyres. Therefore using pure nitrogen will remove moisture which may lead to corrosion – and pressure change.

There are therefore two benefits of nitrogen which will help maintain your accurate tyre pressure for longer – and it is the latter which results in modest savings in fuel and tyre life.

If you decide to try nitrogen your tyres will need filling and purging several times in succession to completely remove air from your tyres, which can be time consuming. PCL’s ACCURA Mobile allows the operator to preset the pressure for a standard inflation top-up, or a purge and fill, so that they can get on with alternative work whilst tyres are inflating.

Once this has been done, do not expect to feel any significant difference unless your tyre pressure was seriously inaccurate before you changed to nitrogen. You may eventually notice some savings in fuel and maintenance costs but remember – this is due to accurate tyre pressure and nitrogen’s ability to help keep it constant.

And for those who are already sold on the importance of accurate tyre pressure, Nitrogen inflation provides enhanced inflation for optimum speed and performance. Just ask Formula 1 drivers!

Easy to use, the unit is operated with an industry standard bottle or direct from a Nitrogen generator and can be preset for a standard inflation top up, or operated with a N2 function for a purge and fill cycle.

Equipped to inflate up to 6 tyres simultaneously, power to the unit is supplied through a sealed battery with the charger allowing the unit to run direct if required, increasing flexibility and enhancing portability.

You can also use Nitrogen with any of PCL’s tyre inflation (or compressed air) equipment.

Those who have already converted to Nitrogen inflation will confirm that once you’ve tried it, you won’t want to use anything else. test

There may be a faulty connector, in this case the faulty connector will need replacing.
