## Description

ESKONKE Retaining Compound Green 638 Sleeve Retainer High Strength Cylindrical Metal Components Assemblies Locking and Sealing Anaerobic Glue 1.69 Oz/50 ml: desertcart.com: Industrial & Scientific

Review: It works as intended. - I was rebuilding the spindles on my mower deck. The bearings were not as tight in the housing as they were when new. So I got this bearing retainer to hold them in. I know that it works because when I went to put the spindles on the deck the shafts were in backwards. I thought, no big deal right ,with as easy as it went together I'll just slide the shafts out and turn them around. Wrong, I had to heat them up on both ends before they would come out, with a precession wrench. They cleaned up easily and went back together well. I know this is a Chinese knock off but but it was within my budget to do the job right.
Review: Great alternative... - Nice alternative to Loctite 638. Grabs quick and holds - had a .007" gap and it filled it, removed wobble, and held tight. Will update later if anything changes, but I intend to use this for many non-threaded fit-ups.

## Features

- Ideal glue for the installation of smooth/unthreaded cylindrical metal assemblies: 1,Fill the voids and reduce the precision requirements of design, production and installation; 2,Prevent assembly from loosening, wear and corrosion; 3,Evenly distribute loads and stresses during assembly; 4,Sealed from oxygen and other contaminants. Extend the life and safe use of the equipment!
- High Strength: After complete curing, Shear strength can be comparable to that of metal materials (609 ≈ Aluminum, 620 & 680 ≈ Copper, 603 & 638 ≈ %0.1 C Steel, 648 ≈ %0.2 C Steel), Ensuring efficient and stable operation of the equipment. Needs to be heated to 250 ℃/482℉ when disassembling, and mechanical auxiliary equipment is required.
- Applicable Scope: Suitable for the assembly of any smooth, unthreaded cylindrical metal components, Such as keys and shafts, bearing, rotor shaft, bushing, casing, cylinder liner, key slot, valve sleeve, movement sleeve, valve bushing etc. Choose the appropriate use according to the characteristics of different models.
- Applicable Material: Suitable for all kinds of solid metals, even metals with active surfaces such as iron, copper, brass, steel, etc. not to mention metals with inert surfaces such as stainless steel, aluminum, gold, etc.
- Simple Use: Just apply the product evenly to the fixed location, the product will start curing within 60 minutes after the assembly is installed, and it can be used normally after 24 hours of standing.
- Function: Fill gaps between components / Lock components to prevent loosening / Prevent component abrasion & corrosion / Improve the accuracy of component fit / Isolate oxygen and prolong product life / Tightness to prevent leakage / Evenly distribute loads and stresses / Repair minor defects in parts / Reduce design and process complexity

## Questions & Answers

**Q: How do I open and close the bottle?**
A: Dear customer, thank you for your question, you only need to forcefully pull the white bottle cap to open the bottle, the white bottle cap has no screws, so turning it to open is ineffective.

**Q: Good for sticking the otter ring/pulley back onto harmonic balancer?**
A: I believe you meant the outer ring or pulley ring that the serpentine belt rides on.  It's not typically used for applications where torque or radial forces are applied.  It's used most often for cylinder sleeve installation or other sleeve type applications or when one needs a thread lock that is beyond red level thread lock.  I've seen repairs for the outer ring on harmonic balancers being made with epoxy like binary adhesion compounds, i.e. JB Weld

**Q: What is required to disassemble the parts? Is heat required?**
A: Dear customer, thanks for the question, When dismantling, it can cooperate with mechanical auxiliary equipment and heat the components to 200~300°C (392~572°F), or it can be dismantled after soaking with special scavenger for a long time

**Q: Can this be used inside an automatic transmission on pressed in bushings?**
A: Will definitely help retain them in place. Get the primer to speed up the cure time.

### ⭐⭐⭐⭐⭐ Great alternative...
*by D***K on February 24, 2026*

Nice alternative to Loctite 638. Grabs quick and holds - had a .007" gap and it filled it, removed wobble, and held tight. Will update later if anything changes, but I intend to use this for many non-threaded fit-ups.

### ⭐⭐⭐⭐⭐ Did very well, Want the secret of the bottle's spout?
*by S***R on February 29, 2024*

It took a little thought to figure out how the bottle's spout works, The outer white cap pull's straight off. inside the outer cap is the dispensing spout. Just pull that spout upward to dispense the fluid, push down to seal it back up. I needed this for a tool that has 2 studs that were glued into the tool body with a very soft glue. The studs popped out when they were tightened, I tried cleaning the surfaces and gluing them with clear Gorilla Glue and the studs popped out again. This retaining fluid worked great after I re-cleaned the surfaces and clamped them in place for 24 hours.
