Drag Block Springs
AS1-X Packer4-1/2" – 5-1/2"
Drag Block Spring — 4.5/5.5" AS1-X
The DRAG BLOCK 4.5 AS1-X is a replacement, redress, and new-assembly drag block spring for AS1-X mechanical set retrievable packers in 4-1/2" to 5-1/2" assembly. This bow spring sits under each drag block in the drag block housing and pushes the block against the assembly wall, so the packer sets and releases with a quarter turn of the tubing. It is made from OEM-grade Inconel 625, which holds its spring force and resists corrosion from H2S, CO2, chlorides and high downhole temperatures. It is a reliable part for AS1-X packer redress kits, workover tools and production packer service.
The DRAG BLOCK 7 AS1-X is a replacement, redress, and new-assembly drag block spring for 7" AS1-X mechanical set retrievable packers used in… production, injection, treating and testing wells. This bow spring sits under each drag block in the drag block housing and keeps steady pressure against the 7" assembly, so the packer’s slips and packing elements set properly. It is made from OEM-grade Inconel 625, which resists sour gas, saltwater, acid treatments and high downhole temperatures without losing tension. It is a dependable replacement for AS1-X packer redress and retrievable packer repair.
The LOWER SLIP 4 1/2 AS1-X is a replacement, redress, and new-assembly slip spring for the lower slips on AS1-X mechanical set retrievable packers in 4-1/2" assembly. This spring holds the lower slips retracted during run-in, then lets them move out over the cone to grip the assembly when the packer is set down. It is made from OEM-grade Elgiloy, which holds its spring force and resists corrosion from H2S, CO2, chlorides and high downhole temperatures. It is a reliable part for AS1-X packer redress kits, workover tools and production packer service.
The LOWER SLIP 5 1/2 AS1-X is a replacement, redress, and new-assembly slip spring for the lower slips on AS1-X mechanical set retrievable packers in 5-1/2" assembly. This spring keeps the lower slips tucked in during run-in so they don’t drag or preset, then lets them engage the assembly when the packer is set in compression. It is made from OEM-grade Elgiloy, which holds its spring force and resists corrosion from H2S, CO2, chlorides and high downhole temperatures. It is a reliable part for AS1-X packer redress kits, workover tools and production packer service.
The LOWER SLIP 7 AS1-X is a replacement, redress, and new-assembly slip spring for the lower slips on AS1-X mechanical set retrievable packers in 7" assembly. This spring holds the lower slips retracted during run-in, lets them expand against the 7" assembly when the packer is set, and helps pull them back in for retrieval. It is made from OEM-grade Elgiloy, which holds its spring force and resists corrosion from H2S, CO2, chlorides and high downhole temperatures. It is a reliable part for AS1-X packer redress kits, workover tools and production packer service.
The UPPER SLIP 4 1/2 AS1-X is a replacement, redress, and new-assembly slip spring for the upper slips on AS1-X mechanical set retrievable packers in 4-1/2" assembly. This spring keeps the upper slips retracted while running in, lets them grip the assembly to hold pressure from below, and pulls them back in on release so the packer comes out of the hole cleanly. It is made from OEM-grade Elgiloy, which resists sour gas, saltwater, acid treatments and high downhole temperatures without losing tension. It is a dependable replacement for AS1-X packer redress and retrievable packer repair.
The UPPER SLIP 5 1/2 AS1-X is a replacement, redress, and new-assembly slip spring for the upper slips on 5-1/2" AS1-X mechanical packers used in… production, injection, treating and testing wells. This spring keeps the upper slips retracted during run-in, lets them grip the assembly to hold pressure from below, and helps them release cleanly when the tubing is turned to retrieve the packer. It is made from OEM-grade Elgiloy, which resists sour gas, saltwater, acid treatments and high downhole temperatures without losing tension. It is a dependable replacement for AS1-X packer redress and retrievable packer repair.
The UPPER SLIP 7 AS1-X is a heavier-gauge replacement, redress, and new-assembly slip spring for the upper slips on 7" AS1-X mechanical packers used… in production, injection, treating and testing wells. Its .012" thickness gives the larger 7" upper slips the extra spring force they need to stay retracted during run-in and to release cleanly when the packer is unset. It is made from OEM-grade Elgiloy, which resists sour gas, saltwater, acid treatments and high downhole temperatures without losing tension. It is a dependable replacement for AS1-X packer redress and retrievable packer repair.
The 4.5-TAC-SLIP is a replacement, redress, and new-assembly slip spring for tubing anchor catchers run in 4-1/2" assembly on rod pumped wells. This spring holds the anchor’s slips in place during run-in, then lets them move out to grip the assembly when the tubing anchor is set by rotation. It is made from stainless steel, a spring-tempered alloy that keeps consistent tension and resists corrosion and rust in typical downhole conditions. It is a reliable part for TAC redress, rod pump well service and artificial lift repair.
The 5.5-TAC-SLIP is a replacement, redress, and new-assembly slip spring for tubing anchor catchers used in 5-1/2" assembly on rod pumped wells. This spring keeps the slips controlled during run-in, lets them grip the assembly when the anchor is set, and helps retract them so the tool can be released and pulled. It is made from stainless steel, which provides strong, consistent spring force and resists corrosion from produced fluids. It is a dependable replacement for tubing anchor redress and artificial lift service.
The 7-TAC-SLIP is a replacement, redress, and new-assembly slip spring for tubing anchor catchers run in 7" assembly. This spring holds the slips in position during run-in, lets them expand against the 7" assembly when the tubing anchor is set, and helps them release cleanly when the tool is unset for retrieval. It is made from heavier stainless steel, which gives the larger 7" slips the extra spring force they need and resists corrosion in produced water and oil. It is a reliable part for TAC redress, rod pump well service and production equipment repair.
The 4.5-TAC-DRAG is a replacement, redress, and new-assembly drag spring for tubing anchor catchers run in 4-1/2" assembly on rod pumped wells. This spring presses against the assembly wall to create the friction that holds the anchor body still while the tubing is rotated to set or release the slips. It is made from full hard 301 stainless steel with a round edge, which gives strong, consistent drag force, resists corrosion, and runs smoothly along the assembly. It is a reliable part for TAC redress, rod pump well service and artificial lift repair.
The 5.5-TAC-DRAG is a heavy-duty replacement, redress, and new-assembly drag spring for tubing anchor catchers run in both 5-1/2" assembly. This spring rides against the assembly wall and supplies the drag needed to keep the anchor body from turning, so the slips set and release properly when the tubing is rotated. It is made from full hard 301 stainless steel, which delivers high spring force and holds its shape in demanding rod pump and production wells. It is a dependable replacement for tubing anchor redress and artificial lift service in both assembly sizes.
