The BEAVER 15 m.m.Wrench  

Mk 3

A new tool specifically designed and developed for 
15 m.m. Plumbing Compression joints

15Description

 

Primary Features 

  • The curves jaws and hook allow it to deal with majority of 15 m.m. compression nuts without needing adjustment.

  • Strong and compact, allowing it to be used in tight spaces.

  • Slim handle can be used to "deburr" pipe ends.

  • Handle easily extendable with a piece of spare pipe.

Benefits 

  • No longer need to carry a range of adjustable spanners.

  • Can be easily used in places impossible with bigger, clumsier tools.
    (Easily slips in a pocket!)

  • Less dismantling to gain access.

  • No need for carrying separate deburring tool / files etc.

-----------------------------------------------

Main Design Points.of 15 m.m.

 15NumberS

1. Pivot Curve – This allows the tool to swing away at it’s base and slide on to the next flat.  Contact is maintained and there is no need to remove the tool in order to fumble for the next flat.  Important where the nut is virtually not able to be seen.

2. Hook – Accommodates “conex” nuts or drives on the walls of conventional nuts.

3. Middle Curve – Extended curve allows tool to accommodate  different sizes and shapes at different points on the curve.

4. Bottom curve –Clearance for tool to pivot (1).  Allowing tool to move to next flat without losing  contact.  
 
(No need to remove tool entirely to  move onto next flat.)  See Ratcheting below.

5. Bottom prong – Either engages with “conex” rib or drives conventional nut on the flat  - similar to top hook.

6. "Hammer" flat.

7. Handle : –
 (A.) Angled specifically so that a line through the middle passes through the centre of the nut to give maximum torque, (turning not swinging), and is as compact as feasible to allow maximum access in tight spaces.

  (B.)  Further designed to allow it to enter and hold a spare piece of 15mm pipe for additional leverage if needed.

  (C.) When a pipe is cut it generally leaves a rough edge inside the pipe. It is necessary to remove these “burrs” if a bending spring is to be used to bend the pipe.
The edges of the handle effectively act as a “deburrer”, cleaning up and smoothing the inside of the pipe end.

8.  2.5 mm slot  for valve stems.

------------------------------------------

Apart from space, the major problem is that the nuts all vary in shape. From ribbed nuts (conex) to six sided conventional nuts that range from under 22 m.m. to over 24.4 across the flats. 

Conventional spanners, driving on the points  fit only a few and risk damaging the nuts. 

NutRange

“Mole” type grips / adjustable spanners are large , clumsy and need constant adjustment.

Adjustable spanners also need constant adjustment, tend to close up when moved to the next flat, and can be confusing to adjust when not in sight. (Upside down etc.)

None of the below are easy or suitable for use in this situation. They are either too big and clumsy, need constant adjustment or simply do not fit very well and risk causing damage. 

Poor Tools

Another major factor is that, due to nature of their deployment, the fitting are generally awkward to access.  Being sited at the back of cupboard / very close to other fittings etc.

           TightSPace

Wouldn't it be extremely useful to have a single tool that would fit them all?     
And one that is small and compact enough to use without having to dismantle other bits to gain enough space. 

There is now!

15Description

This BEAVER is designed to drive primarily on the flat of the nut. The complex curve allowing it to automatically accommodate and adjust to different sizes and shapes.      

         “Conex” Ribbed nut                                       Large Nut (24.23 m.m.)

      Conex                Large

    Middle Size (22.43 m.m.)                                   Smaller Nut (21.99 m.m.)

  Middle              Small

 

The short handle, and head to handle curves, allow the tool to be used even between  tightly spaced pipes.

Ratcheting

Another common problem often encountered with conventional spanners  (especially in difficult situations where the joint is virtually hidden) is moving it to the next flat.  You made a first small turn of the nut then, due to space limitations, have to disconnect and move the spanner around.  You then have to search and probe around to get the spanner fitted.
Perhaps have to loosen off an adjustable to fit then tighten it again.

With the "BEAVER" the top and bottom jaws form a wedge. It locates itself.

The bottom curve allows it to swing away pivoting on the top curve. 

The hook then slides across the flat, over the point of the nut, and locates on the next flat.

      Rachet

It does not need to be removed entirely.  So, if it is difficult to see the fitting, you do not have to lose contact. 

  Each BEAVER is laser cut from 6 m.m. thick steel to ensure accuracy and a smooth
  edge.

DeBurring pipes.

 Using a Pipe Slice / Hacksaw etc almost invariable leaves a jagged or belled (in) end 
 on the pipe.

 This needs to be removed either for a clean joint or to insert a pipe bending spring.  

 The handle is specifically designed to achieve this without having to resort to files or
 a Pipe Deburrer.  (or those poor triangle fittings found on some pipe cutters!)

     

     End of Pipe belled inwards               Insert end of handle and twist gently    
                                                            pushing it inwards. The four edges of the 
                                                            handle "clean up" the pipe. 
.                                                                       

     

            Pipe "burr" removed.                          Allowing spring to be used.

Supplementary Info.

 If you need a longer handle simply slip on a suitable piece of spare tube.

15handle

 Due to the tool driving on the flat of the nut it stays in place even when hanging nearly
 vertical.  

  

 It can even be used on the plastic nuts that fasten toilet seats!
