F/R Coupling Procedure

Niedner’s REELTEX® field repairable coupling is designed to give long service life providing it is properly installed and maintained. It may be detached and re-attached many times and may be used as either an end coupling or as a means of splicing two or more damaged sections of hose together.

Make sure you have the following parts and tools before proceeding:

  • 4 - Half collars

  • 1 - Male shank

  • 1 - Female shank

  • 8 - 3/4” or 1” long stainless steel Allen head cap screws 10-24 thread

  • 1 - 5/32” Allen head wrench or screwdriver

  • 1 - O-ring each male and female shank.(2 each for the 1” coupling shank)


Installation of REELTEX® field repairable couplings:

  • Trim the ends of the REELTEX® hose square with a sharp knife. (The helical reinforcement may have to be cut with a wire cutter).

  • Verify that the rubber O-rings on each shank are not cut or damaged. If they are they must be replaced. Slip the hose over the shank of either the male or female coupling. It should extend no farther than 3 grooves beyond the rubber O-rings. If the hose is difficult to slide onto the shank, a little petroleum jelly may be used to facilitate this. DO NOT use oil or grease, as they will attack the inner tube and cause eventual leakage.

  • Place two of the half collars over the hose and thread the four 10-24 cap screws into place finger tight. Note that the chamfered end of the collars goes towards the back of the coupling.

  • Tighten each of the four bolts gradually in crisscross pattern until they are all snug. Do not over tighten as this may strip the threads in the aluminum half collars. When properly tightened, there should be a very slight gap between the collars. This is normal providing the gap is the same on each side. It is important that the bolts be tightened alternately and evenly

In order to detach the coupling set, remove the 4 bolts and the two half collars. The hose will be difficult to remove from the shank and will probably need to be cut off. In doing so, pay careful attention not to damage the rubber O-rings.

WARNING
The REELTEX® field repairable coupling is designed and intended to be installed only on Niedner REELTEX® hose and as such no attempt should be made to attach it to any other brand of hose. Attachment to another type of hose could result in coupling slippage or blow off which could cause damage or serious injury. Niedner assumes no responsibility for any coupling assembly that does not respect the above installation instructions.

Replacement parts may be ordered as required. Please refer to the following part numbers when ordering and do not forget to stipulate the required number of pieces.

At Pumpkin Center VFD, we strive to give our members quality equipment to use at all times. We’ve found over the years that small details make huge differences. Our equipment committee is always asking the question “Is something better out there?” We stay abreast of current industry trends and investigate the latest and greatest from equipment manufacturers to make sure our guys and girls have what they need to do the job and do it well. In 2009 we were tired of the fire hose we had been purchasing and bought some Niedner XL-800. The hose is still in service today. During this time we’ve found that in addition to being durable, it rolls up extremely tightly, packs tightly in hose beds and is lightweight, which lessens fatigue on members. With a comparable friction loss rate to much other hose in the industry, our committee has yet to find a reason to leave Niedner. We had several sections of cloth Niedner 4 inch supply hose before switching to 5 inch as well. It was the best supply hose I’ve ever seen or used.
