Locking Mandrels from Western Pressure Controls

Locking mandrels, or locks, play a key role when it comes to downhole equipment. Locking mandrels are anchored within the tubing string and provide a setting point for equipment like chokes, valves, or plugs.

Western Pressure Controls offers a wide variety of locking mandrels incredibly useful to the industry, in both Baker and Otis-styles.

Here is a comprehensive list of the tools we offer:



Designed to be run on a C-1 running tool, this type of lock has dogs that prevent upward or downward movement. This product is available in sizes for 1.50” to 3.5”. It is available with “T” keys for use in collars.

W & Z Locks

This is a selective lock that prevents upward movement with a set of dogs. The “W” lock downward movement is prevented by a no-go on the lock body. Similarly, the “Z” lock downward movement is prevented by a no-go on the equalizing assembly. These tools are available for H2S service and with “T” keys for use in collars.



The type D lock mandrel is used to land and lock in an API tubing collar, and to seal it at set positions to maintain a pressure differential from above and below. The sealing element is mechanically locked in the collar and can be used in conjunction with pump thru valves, standing valves, or choke assemblies. The standard D lock configuration is equipped with a knockout kobes to equalize pressure differentials previous to pulling. Specifications are available upon request.


This tool is designed to lock into an “N” nipple of its corresponding size. This tool can be set to hold pressure from above or below in one run. Specifications are available if needed.



This tool is used to selectively set in any type “R” landing nipple of the same size, and is available in R and RN profiles. Packing mandrels have a metal to metal seal and are available in sizes 2.563” or larger.


X-locks are used to set in any type X landing nipple or XN of the same size, and are available with the interference mandrel upon request. This tool is available in various metals, including L-80, Stainless Steel, 13Cr and Incoloy. For more information on pricing and availability, contact us at Western Pressure Control.

Tool String Equipment from Western Pressure Controls

Tool strings are vital in the safety, maintenance, and success of wireline worksites. These tools are used to set, service, and pull downhole equipment. Western Pressure Controls offers a wide variety of tool string equipment incredibly useful to the industry.
Here is a comprehensive list of what we offer:

Centralizer: This tool is used to hold the tool string in the middle of the hole. Specifications are available upon request.

Chisel: This tool is used to break up cement, scale, hydrates, rubber, and other debris that may be in the way of the wellbore.

Broaches: Used to remove burrs and bumps in the tubing caused by perforations, rust, bent or crimped tubing, this tool is offered in pineapple and profile styles.

Knuckle Jars: This tool provides flexibility and light jarring in the wireline.

Knuckle Joint: No, this is not part of the human anatomy. Knuckle joints help provide angular movement between segments of the tool string.

Line Cutters—Cam Cutter: This tool is assembled around the line at the well surface and rides down the well on the line. It cuts the line once it reaches the stopped tooling.

Quick Connect: Without the use of threads, quick connects are fast and efficient to connect tools together.

Rope Socket: Available in wedge and sleeve, button and spool, slip and clamp styles, rope sockets are used to securely tie the wireline to the tool string.

Roller Stem: Use this tool in place of high density weight bars to improve horizontal movement.

Stem/Sinker Bar: This tool has two purposes: to deliver weight impact during tool operation, and to overcome well pressure in running tools down the wellbore.

Swab Bore: Available in slot style or ball check style, this tool is used to retrieve fluid from the wellbore.

Swedging Tool
The swedging tool is used to expand collapses or bends in tubing back to optimal operating size.

Swivel Joint: This tool allows the tool string to rotate without rotating the line or threaded connections.

Tube Jar: The tube jar has the same use as a spang jar, but is used when the spang jar is impractical. Shock absorbers are used to avoid a jarring motion when the tool string is pulled or lands abruptly on a surface.


Tubing Brush: This tool scrapes at the tubing wall or profile to remove unwanted dust and debris.

Tubing End Locator: As its name entails, this tool is used to locate the bottom of the tubing, and to take samples from the well.

Wax Knife Without Wires: Similar to the tubing brush, this tool is used to scrape at the tubing wall and remove unwanted debris and build up. It is available in three sizes: 0.750″, 1.000″, and 2.375″.

If you have any questions regarding these tools, we at Western Pressure Controls are happy to help. For more information regarding our services, contact us today.

The Best BHP Equipment from Western Pressure Controls

Western Pressure Controls provides some of the highest quality BHP Equipment on the market today. If you are in the wireline tool business, BHP equipment is crucial to your operation.

Here are some BHP accessories offered at Western Pressure Controls:


This tool is used to provide a protective housing against vibrations, fluids, and corrosive elements for downhole equipment. It is offered in the standard 60″ length although specific lengths and thread connections are available upon request. If required, the bullet nose can be replaced with a thread connection.

Collar Stops

This tool provides a solid footing and anchor in tubing. Its legs are held in place by the trip wires and released when jarred upwards. Jarring downwards will set the collar stop and release the running tool. This tool is wireline retrievable.

Hold Downs (No-Blows)

The purpose of this tool is to prevent the instrument carrier from being pushed up the well by a sudden burst of gas, fluid or debris. Cam pin #8 is sold on the assembly with cam #7.

J-Unlatching Tool

This tool is designed to set instrumentation into the well bore in conjunction with a WPC “J” unlatch head fishneck. This process is done at a pre-determined depth without having to jar to release.


Used in conjunction with the J-unlatch running tool, the J-head tool lands recording instrumentation and other equipment in the well using a shear-type running tool. This eliminates the need for jarring action to release equipment.

No-Go Darts

These flute darts are commonly used as platforms to set on profile nipples. Recorders and other instrumentation are then set on the platform. This tool is available in gauge-ring and non-threaded fishneck styles.

Tubing Stops

The tubing stop has numerous wireline applications. It can be used like a flute dart and serve as a platform for recorders and other instrumentation, or to secure equalizing equipment. These are also available with ratchet locking bodies to ensure no premature unsettling that might be caused by flow or vibration.

This tool is available in a ratchet-style locking body, or a BKO sleeve for baker-style lock bodies.

At Western Pressure Controls, we ensure the highest quality in wireline tools and equipment, both domestically and internationally. For more information, or to speak with a trusted professional, contact us today.
