At Western Pressure Controls, we offer a variety of surface equipment for the wireline community, both domestic and internationally. Here are some of the best surface equipment tools on the market from Western Pressure Controls:

Bleed Off/ Purge Sub

This tool is typically used at either the top joint of the lubricator as a Nitrogen sub to pressurize and eliminate the presence of dangerous or flammable gases contained in the lubricator, or as a bleed off sub at the bottom of the lubricator to bleed off gasses to the vessel or tank. This tool can take up to 5,000 psi working pressure, with single or dual ½” npt ports.

Night Cap/Lifting Cap

This tool is designed to secure the wellhead over night and gauge pressures, and used to lift surface equipment into place on the wellhead and other equipment that may not be easily accessed. This tool can withstand up to 5,000 psi working pressure, contains a ½” npt bleed port, and N.A.C.E. spec.

Pump-in Sub

The pump-in sub is used for injection of bleed-off fluids or pressure in a well. Part #2 of this tool can be modified to fit the customer’s specifications. This tool can withstand up to 5,000 psi working pressure, contains a ½” npt bleed port, N.A.C.E. spec, and 4 3/4” TPI connections.

3” Wireline Valve – Manual and Hydraulic

This tool is designed to equalize and isolate pressure to the lubricator with the wireline still connected to tools in the wellbore, allowing the operator to bleed off the lubricator without releasing well gases into the atmosphere and allowing access to the wireline contained in the lubricator. The standard coating for this tool is Teflon, and nickel coating is available upon request.

Line Oiler

This tool can be used to treat wireline and corrosion inhibitors to protect against H2S or CO2 corrosion. Inserts are available in brass, nylon, or aluminum bronze.


The lubricator houses the wireline toolstring and contains pressure during wireline operations. It is available in multiple lengths with bleed-off subs. This tool is available in multiple lengths with a bleed-off sub.

 10” and 16” Stuffing Boxes

Wellhead Heaves (Hay Pulley)

This tool redirects the wireline to the stuffing box sheave and provides a guide for the wireline. The 16” hay pulley is available with a quick release safety hook in place of the clevis upon request. It is pull-tested to meet and exceed industry standards.
