Box-Guide in 2-7/8" Tubing


Box-Guide in 2-3/8" Tubing


The Box-Guide is a guided sucker rod coupling (rod centralizer) featuring our MP Polymer Technology. The extreme wear and chemical resistance, plus high-temperature service range are benefits of the MP Polymer that provide our guided sucker rod couplings with outstanding product life. The Box-Guide allows the consumer to take RFG’s mold-on sucker rod technology and gain superior protection in a field-installed rod guide application.

Box-Guide Installation

Installation of Box-Guides couldn’t be easier. RFG designed these tools to be a seamless integration at the well-site. Power tongs work around them without issue. Just be sure to check for clearances with the gear-set on location. The Box-Guides have molded plastic around the coupling, and sharp impact to them from heavy tools and impact can damage the guided coupling.

Box-Guides also work directly with Rod Transfer Tools when hanging rods in the racks. We’ve found some old transfers in the marketplace have a smaller internal clearance which typically can be overcome by turning the rod 90 degrees before placing into the rod transfer.
