Top 8 Sealing Recommendations for Guanlu Machinery

Based on Guanlu's core markets — hydraulic cylinders, oilfield equipment, coal mining supports, molds, automotive, and aerospace — these Fluidseal AB product categories address the most critical sealing needs across the equipment Guanlu builds and the industries it serves.

Metric / Piston Seals
Metric Piston Seals
PB, PB/N, P5B, P2B, P4A (and others)
High
Guanlu's BTA and SRB machines produce precision hydraulic cylinder bores up to 800 mm diameter. Metric piston seals are the primary dynamic seals riding inside those bores, making this the highest-priority product family for Guanlu's hydraulic cylinder and coal mining customer end-users.
Hydraulic cylinders, servo cylinders, industrial cylinders, and coal mining support cylinders manufactured on Guanlu BTA drilling and SRB machines. Shop →
Metric / Rod Seals
Metric Rod Seals
RC, RA, RX, RZ, RV, SD/N ST/N (and others)
High
Hydraulic cylinders and piston rods — a core output of Guanlu's machines — require reliable rod seals to prevent fluid leakage along the reciprocating rod. The broad metric series range covers the cylinder bore diameters Guanlu machines produce.
Precision piston rods, hydraulic valve block actuators, and industrial cylinder rod glands in hydraulic and oilfield equipment. Shop →
Metric / Rod Wipers
Metric Rod Wipers
WA, WC, WT, WW, WN, WO (and others)
High
Rod wipers (scrapers) are installed at the outer edge of cylinder heads to exclude contaminants from entering the hydraulic system. Guanlu machines finish cylinder bores for hydraulic, coal mining, and oilfield applications — all environments where contamination exclusion is critical.
Hydraulic cylinders, coal mining movable columns, oilfield drill-collar housings, and industrial actuator cylinders. Shop →
Metric / Guiding Elements
Metric Guiding Elements (Wear Rings / Guide Bands)
GC, GB, GB/N, DU, DZT (and others)
High
Guiding elements (wear rings) center the piston and rod within the cylinder bore, preventing metal-to-metal contact. Guanlu produces precision bores up to 800 mm — exactly the range where guide bands are essential for long-stroke hydraulic and mining cylinders.
Hydraulic cylinders, servo cylinders, coal mining supports, and large industrial actuators using Guanlu-machined precision bores. Shop →
Metric / O-Rings
Metric O-Rings
O'ring M (metric standard), Quad Rings, Usit Rings, O-Ring Cord
High
O-rings are the universal sealing element for static and dynamic faces throughout hydraulic valve blocks, cylinder end caps, and port connections. Guanlu machines drill hydraulic valve block oil-way holes — each port face requires an O-ring for assembly.
Hydraulic valve block port sealing, cylinder end-cap static seals, and machine tool coolant circuit joints on Guanlu-supplied equipment. Shop →
Metric / Shaft Seals
Metric Shaft / Rotary Seals
TC, SC, TB2, SA2, VC, VB (and others)
Medium
Guanlu's deep hole drilling machines and the equipment they produce — including gun drill spindles and hydraulic pump/motor shafts — require rotary shaft seals to retain oil and exclude contaminants at rotating interfaces. High oil pressure (>10 MPa) cited for micro-hole gun drilling confirms active shaft sealing needs.
Main spindle assemblies on Guanlu machines, hydraulic pump/motor shaft sealing, and rotating interfaces in energy and oilfield equipment. Shop →
Gasket / Flange Gasket
Flange Gaskets (Full Face & Ring Type)
Full Face, Ring Type
Medium
Flange gaskets are required wherever fluid lines and manifolds are flanged together — common in the hydraulic, oilfield, and energy sector equipment that Guanlu's machines are designed to produce (e.g., heat exchanger tube sheets, oilfield drill-string connections). Both full-face and ring-type configurations are stocked.
Hydraulic manifold flanges, heat exchanger tube-sheet joints, oilfield drill-collar pipe connections, and energy turbine-shaft assemblies. Shop →
Sealant and Adhesive — Vibra-Tite
Vibra-Tite Sealant & Adhesive
Vibra-Tite product line
Medium
Thread-locking sealants and adhesives are used during assembly and maintenance of deep hole drilling machines and the precision cylinders they produce — securing fasteners against vibration on machine tools, and sealing hydraulic port threads to prevent weeping under cyclic pressure.
Thread sealing on hydraulic port fittings, fastener retention on machine tool assemblies, and maintenance of hydraulic valve blocks and cylinder end caps. Shop →
