RIDGID No. 40-A Portable TRISTAND Yoke Pipe Vise, 1/8–2-1/2 in. Capacity, Folding Tripod Stand, Catalog 40130

Condition: Used. Heavy cosmetic wear from prior shop/field use, including chipped and worn red/black paint, surface oxidation, dirt, scratches, and finish loss.

Description

The RIDGID No. 40-A TRISTAND is a heavy-duty portable pipe-working stand built around an integrated yoke-style pipe vise. The cast work platform incorporates the vise, pipe-support features, bending forms, tool-storage provisions, and folding tripod legs, allowing plumbers, pipefitters, HVAC technicians, mechanical contractors, and maintenance crews to create a stable pipe-working station at the jobsite.

RIDGID lists the 40-A for pipe from 1/8 in. through 2-1/2 in. (3–60 mm) and gives the complete stand a nominal weight of 48.5 lb (22 kg). The manufacturer specifically describes the 40-A as integrating a yoke-style vise into the base together with a rugged tool tray.

The pictured example is an older, well-used unit with clear field wear. Its substantial cast platform, steel tripod legs, threaded vise screw, fixed and movable jaws, triangular lower tray, and folding construction make it suitable for holding pipe during cutting, threading preparation, reaming, fitting, and related mechanical work.

Features

• Catalog number: 40130
• Tool type: Portable tripod pipe vise / pipe work stand
• Vise style: Yoke vise
• Pipe capacity: 1/8–2-1/2 in.
• Metric pipe capacity: 3–60 mm

RIDGID’s current TRISTAND instructions describe the family as having tool hangers, an equipment tray, pipe benders, and a jackscrew for stabilization. The stands fold for storage and transport.

Applications

The RIDGID 40-A is intended for holding pipe securely while performing common fabrication and service operations. Typical applications include:

• Plumbing installation and repair
• HVAC hydronic and mechanical piping
• Commercial mechanical contracting
• Pipe fitting and fabrication
• Pipe cutting
• Reaming and deburring
• Manual threading preparation
• Fitting assembly and disassembly
• Pipe measurement and layout
• Maintenance departments
• Boiler and mechanical-room work
• Industrial plant maintenance
• Construction-site pipe preparation
• Fire-protection piping service
• Facility maintenance
• Utility and service work

The manufacturer cautions that tools used on carbon-steel pipe can contaminate stainless steel and recommends dedicated equipment or proper cleaning when switching materials.

Assembly and System Use

The 40-A is a complete portable workholding system rather than merely a vise head. Major assemblies identified in RIDGID parts documentation include the base, legs and tray assembly, triangular tool tray, yoke and hook assembly, yoke assembly, front and rear legs, leg chain, feed screw, jackscrew assembly, upper jaw, and lower jaw set.

It can therefore serve as the pipe-holding station for a larger manual or powered pipe-preparation workflow involving cutters, reamers, threaders, wrenches, and fitting tools. RIDGID also notes that tripod feet can be anchored for increased stability and specifically recommends anchoring when stands are used with geared threaders or large/heavy pipe.

Cross-Referenced Models

• RIDGID 40-A / Catalog 40130 — yoke vise, 1/8–2-1/2 in. capacity, 48.5 lb
• RIDGID 425 / Catalog 16703 — chain vise, 1/8–2-1/2 in. capacity, 32 lb
• RIDGID 460-6 / Catalog 36273 — chain vise, 1/8–6 in. capacity, 42.75 lb
• RIDGID 460-12 / Catalog 36278 — chain vise, 1/8–12 in. capacity, 60.75 lb
• RIDGID 450 / Catalog 40160 — older 1/8–5 in. portable TRISTAND chain-vise model; RIDGID lists this model as obsolete.
• RIDGID 460 / Catalog 72037 — older 1/8–6 in. portable TRISTAND chain-vise version; listed by RIDGID as obsolete.

Comparable Products

The RIDGID 425 is the closest same-capacity alternative where a chain-style vise is preferred over the 40-A’s yoke. It retains a 1/8–2-1/2 in. capacity but is considerably lighter at 32 lb.

For larger-diameter pipe, the RIDGID 460-6 increases capacity to 6 in., while the 460-12 accommodates pipe up to 12 in. These use chain vises rather than the yoke mechanism fitted to the 40-A.

Comparable general product descriptions from other manufacturers would include portable tripod pipe vises, folding pipe work stands, yoke-style pipe stands, chain-vise tripod stands, and field pipe-threading support stands. Exact interchangeability of replacement parts between manufacturers should not be assumed.
