“XL just means it is a little longer and might reach a little farther into CVU joints. All other aspects are the same.
The KYPlus mechanism is nearly all internal. Therefore eliminating the awkwardness of getting attached to some zerk locations. Attaching only requires a straight on push and it is engaged. Diaengaging from a zerk that has locked itself to the coupler due to excessive internal pressure is where other couplers become damaged and then begin to leak. The KYPlus releases that pressure and the coupler comes off easily, as always. No wrenching or twisting is ever required. The full metal face that meets the flat metal face of a zerk will always want to match face to face with the zerk. If the zerk is worn and the face is not perfectly flat, leaking will occur and the zer should be replaced. At times, there are situations where a 90 degree connection must be made because of space limitations. As of now, Macnaught does not offer a 90 degree adapter. Those adapters can be found online but so far as I have been able to find, they use a rubber seal, but for the few grease points where a 90 is required, you could either purchase an adapter or change the zerk to 90 degrees.”
“Just bought a new trailer with pressed in grease fittings which pulled right out with my traditional coupler. The Macnaught releases very easy without pulling the zerks out, a big plus!”
Thank you for your fantastic review, Jeff! We're glad to hear that the Macnaught KYPLUSXL Safety Locking Grease Coupler is working so well for your new trailer. Your satisfaction means a lot to us, and we look forward to serving you again!
“I have used lock n Lube for years, and this coupler is much easier to use.. Easy to click on instead of holding a lever. Sometimes, it takes a little tug to remove, but boy, it is an easy tradeoff.”
